Parabolic reflectors for sale are used to collect energy from a distant source (for example sound waves or incoming star light). Since the principles of reflection are reversible, parabolic reflectors can also be used to focus radiation from an isotropic source into a narrow beam. In optics, parabolic mirror are used to gather light in reflecting telescopes and solar furnaces, and project a beam of light in flashlights, searchlights, stage spotlights, and car headlights. In radio, parabolic antennas are used to radiate a narrow beam of radio waves for point-to-point communications in satellite dishes and microwave relay stations, and to locate aircraft, ships, and vehicles in radar sets. In acoustics, parabolic microphones are used to record faraway sounds such as bird calls, in sports reporting, and to eavesdrop on private conversations in espionage and law enforcement.

Parabolic mirror for sale are typically designed as a segment of a larger parabola, manufactured from a metal substrate such as aluminum and coated in enhanced aluminum, silver or gold as standard. These mirrors focus light similar to a concave mirror with the significant exception being that the off-axis parabolic mirror design redirects the incident light through 90%.

Custom mirrors may be manufactured in a range of substrates and alternative coatings as required by our customer's specifications including UV and IR coatings and materials and alternative reflection angles.

Basic Tips about Aspherical Lenses(2024年04月13日)

hypoptics — 2024-04-11T16:50:48+0900

http://www.hypoptics.com/basic-tips-about-aspherical-lenses.html

The curvature of the lens of this kind of lenses is better. It maintains the good performance of aberration correction to obtain the required performance. The use of aspheric lenses brings outstanding sharpness and higher resolution, while miniaturization of lenses is possible.

Summary:
Aspherical lens is a constant curvature from the center of the lens to the edge, but the curvature of the lens varies continuously from the center to the edge for aspherical lenses. In photographic lenses, many aberrations must be corrected in order to ensure optical performance. If only the aspherical lens is used to correct the lens, the technical requirements of the lens require a combination of lenses. For special advanced lenses, only spherical lenses sometimes fail to correct aberrations to the level of user satisfaction. Calculation formulas in optical design:

Calculation formulas in optical design
Technical principle:
The radius of curvature of an aspherical lens varies with the central axis to improve optical quality, reduce optical elements, and reduce design costs. Aspheric lenses have unique advantages over spherical lenses, so they are widely used in optical instruments, images and optoelectronics industries, such as digital cameras, vehicle lenses, and high-end micro instruments.

Comparative advantage:
A. aberration calibration
The most prominent advantage of aspheric lenses in replacing spherical lenses is that they can correct the spherical aberration induced by the spherical lens in the collimation and focusing system. By adjusting the surface constant and the aspheric coefficient, the aspheric lens can eliminate spherical aberration to the maximum extent. Aspherical lenses (rays converging to the same point, providing optical qualities) essentially eliminate spherical aberrations produced by spherical lenses (which converge to different points, leading to blurred imaging).
Three spherical lenses are used to increase the effective focal length for the elimination of spherical aberration. However, an aspheric lens (high numerical aperture, short focal length) can be implemented, and the system design is simplified and the transmittance of the light is provided.

B. system advantage
The aspheric lens simplifies the involved elements adopted by the optical engineers in order to improve the optical quality. And improves the stability of the system. For example, in the zoom system, typically 10 or more lenses were used (additional: high mechanical tolerance, high additional assembly procedures, improve the anti-reflective coating), but 1 or 2 pieces of aspheric lens can realize optical quality similar or better, so as to reduce the system size, improve the cost rate, reduce the comprehensive cost system.

Molding process:
A. precision glass molding
Precision glass molding is the process of heating glass materials to high temperatures and becoming plastic. They are formed by spherical molds and gradually cooled to room temperature. At present, precision glass molding is not suitable for aspheric lenses with a diameter greater than 10mm. But new tools, optical glasses, and measurement processes are driving the technology. Precision glass molding, although the cost is high in the design stage (high precision mold development), but after the molding, the production of high-quality products will average the cost of development and the price will become acceptable, especially suitable for the needs of mass production occasions.

B. precision polishing molding
Grinding and polishing are generally applied to the production of monolithic aspheric lenses at one time. With the improvement of technology, the accuracy of lapping and polishing is higher and higher. Most notably, accurate polishing is controlled by the computer and automatically adjusted to optimize parameters. If higher quality polishing is required, magneto-rheological finishing will be adopted. Compared with standard polishing, magneto-rheological finishing has higher performance and shorter time. Precision polishing molding requires specialized equipment and it is currently the primary choice for sample making and small batch testing.

C. mixing molding
The spherical surface of an aspherical lens is cast on by using a spherical molding, and a layer of high polymer aspheric surface is cured by ultraviolet light and cover on it. In hybrid forming, the achromatic spherical lens is used as the base, and the surface is cast with a layer of aspheric surface to eliminate chromatic aberration and spherical aberration at the same time. Fig. 7 is a manufacturing process of a mixed forming aspherical lens. The hybrid aspherical lens is suitable for occasions where additional characteristics are required (simultaneous elimination of chromatic aberration and spherical aberration) and mass production.

D. injection molding
In addition to glass aspheric lenses, there are plastic aspheric lenses. Plastic molding is the injection of molten plastic into an aspherical mold. Compared with glass, the thermal stability and compressive resistance of plastics are poor, and special treatment is needed to obtain similar aspherical lenses. However, the most important feature of the plastic aspheric lens is its low cost, light weight, and easy molding. It is widely used in such fields as moderate optical quality, insensitive thermal stability, and little pressure resistance.

Selection basis:
Various types of aspheric lenses have their own relative advantages. Therefore, for different applications, it is important to choose the right product. Major considerations include batch size, quality, and cost.
A. precision glass molding aspheric lens has the characteristics of mass production and high thermal stability, suitable for a large batch, high quality, and high thermal stability.
B .precision polishing molding aspheric lens has the characteristics of short period sample preparation and no die need, it is suitable for sample production and small batch sample occasions
C. mixed molding aspheric lens with the features a simultaneous calibration of spherical aberration and chromatic aberration features, suitable for wide spectrum, large volume, high quality.
D. plastic aspheric lens has the characteristics of low cost and light weight, suitable for large quantity, the low requirement on quality, moderate thermal stability.
When aspheric lenses are required (without standard products or inventory products), development costs, sample costs, batch prices, delivery cycles and other factors should be taken into account.

Why Use Achromatic Lens?(2024年04月12日)

hypoptics — 2024-04-11T16:50:11+0900

http://www.hypoptics.com/about-us/resources/why-use-achromatic-lens.html

Achromatic lens is a kind of lens which is made up of two kinds of optical components: positive low refractive index and negative high refractive index. Compared with a single lens containing only a single glass, the dual-lens design can provide additional design freedom for users and further optimize the performance of the lens. Therefore, achromatic lens has more advantages than single lens with equal diameter and focal length.

Achromatic lens has various configurations, among which positive achromatic lens, negative achromatic lens, three-in-one achromatic lens and non-spherical achromatic lens are common. It is important to note that achromatic lenses can be bichromic (dual elements) or triad (three elements), and the number of elements is independent of the number of light corrected by the lens. In other words, double or triple achromatic lenses can correct both red and blue light in the visible range.

The acromatic lens is far superior to the simple multi-color "white light" imaging lens. The two components that make up an achromatic lens (literally "uncolored lens") are combined to correct the inherent chromatic aberration of glass. The achromatic lens is very cost-effective in multi-color illumination and imaging because it can eliminate the difficult chromatic aberration.

Since the axial performance of achromatic lens is not degraded by using larger aperture, it is unnecessary to "reduce" the volume of optical system. "Reducing" aperture refers to reducing the aperture of a lens, such as through a pinhole or aperture, to improve the overall performance of the lens. By making full use of the whole aperture, achromatic lens and achromatic lens system can achieve faster speed, higher performance and more powerful functions than the equivalent system using single lens.

The Design Principles of Infrared Optical System(2024年04月11日)

hypoptics — 2024-04-11T16:46:05+0900

http://www.hypoptics.com/about-us/resources/the-design-principles-of-infrared-optical-system.html

The infrared optical system refers to the system that works in the infrared band of the optical wave, which is the optical system that receives or sends infrared light waves. In general, the infrared optical system is a category of optical system, which is not different from other optical systems in light energy reception, transmission, imaging and other optical concepts. However, due to the infrared optical system working wavelength infrared region and the photoelectric detector as the receiving element, so it has its own characteristics, different from the general optical system.

The wavelength range of infrared optical system tends to be wide, and there are few kinds of infrared transmission materials available at present. Aberration correction, especially chromatic aberration, is very difficult. Therefore, the infrared optical system adopts the non-spherical reflection system or refraction - reflection system in the structure. With the continuous expansion of infrared application scope and the continuous development of infrared thermal imaging technology, the projective objective cannot meet the requirements of large field and large aperture. Therefore, in recent years, high refractive index and low dispersion crystal materials have been widely used for various refractive lens. Infrared optical system is an infrared detector. In order to improve the detection sensitivity, increase the signal-to-noise ratio, the system USES the package live immersion lens, field lens and light cones of secondary condensing system (also known as detector optical system), and a light engine scanning with all kinds of optical scanner. From the principle of design, most infrared optical systems are designed using geometrical optics.

The characteristics of infrared optical system

Because of the unique properties of infrared radiation, compared with the general optical system, especially the visual and photographic system, the infrared optical system have different characteristics.

1) the radiation band of infrared radiation source is located in the invisible zone above 1 um. Ordinary optical glass is not transparent to 2.5 um. In all materials that are possible to penetrate infrared wavelengths, only a few materials have the necessary mechanical properties and can be given a certain size. This greatly restricts the application of lens system in the design of infrared optical system, which makes the reflection type and the reflex optical system occupy a more important position.

2) nearly all infrared systems are optoelectronic systems. Its receiver is not a person's sleep or a photographic plate, but a variety of optoelectronic devices. Therefore, the performance and quality of the corresponding optical system should be based on the sensitivity and signal-to-noise ratio of the optical system, rather than the resolution of the optical system. This is because the resolution tends to be limited by the size of the photoelectric device, thus reducing the requirements for the optical system accordingly.

3) small field and large aperture. In the case of the application unit detector, because the infrared detector has smaller reception area, the optical field of the general infrared optical system is not very large, and the outer aberration of the axis can be considered less.
Because the reflection system has no color difference, in most cases, it is possible for such a reflection system to eliminate the ball and satisfy the sine condition. At the same time, the requirements of such system objects are not too high, and they require high sensitivity. Therefore, most of the optical systems with large relative aperture, namely small F, are adopted. In general, due to the limitation of processing, the number of F is 2-3.

4) the application of various scanners has become more and more, in order to achieve the goal of scanning the space target by tracking the heating of the imaging and thermal imaging technologies. The scanner can be placed before the imaging system, which has a large size and high power consumption, but has minimal impact on the image quality of the optical system. In addition, the optical system with this scanning system requires the rear focal length of the principal and some special requirements for the it.

5) the wavelength of the infrared band is about 5-20 times that of visible light. In this way, the temperature of the thermal imaging system is lower because of the diffraction limit, which means that the thermal imaging system with high resolution must have a large aperture. This makes the system heavy and costly.

Notch Filter(2024年02月23日)

hypoptics — 2024-02-23T12:09:51+0900

http://www.hypoptics.com/components/filters/notch-filter.html

The notch filter, in contrast to a narrow band filter, intercepts light in a particular wavelength range by transmitting light at most wavelengths.

Notch filters are useful in applications where it is necessary to filter out the laser light. For example, in drug bioassays, in order to obtain a good signal-to-noise ratio in Raman spectroscopy experiments, it is necessary to suppress the pumping laser, which can be achieved by placing a notch filter on the detection channel. Notch optical filters are also often used in laser-based fluorescence instruments and in biomedical laser systems.

The core requirements for filters used in fluorescence detection systems are high cut-off steepness, high transmittance, high positioning accuracy, high cut-off depth, and excellent environmental stability.

Fluorescent filter is a combination of three, three are excitation filters, emission filters and dichroic filters.

Excitation Filter (Exciter Filter, Excitation Filter, Excitation Filter): In the fluorescence microscope, only the excitation wavelength of the filter can pass through the fluorescence. In the past, a short-pass filter was used, and now a band-pass filter is basically used. The housing is marked with arrows indicating the direction of propagation of the recommended light.

Emission Filter (Emitter Filter, Emitter): Select and transmit the fluorescence emitted by the sample, the other range of light cut-off. The wavelength of the emitted light is longer than the wavelength of the excitation light (closer to red). A band-pass filter or a long-wave-pass filter may be selected as the emission filter. The housing is marked with arrows indicating the direction of propagation of the recommended light.

Dichroic Mirror (Dichromic Beamsplitter, Dichromatic Beamsplitter): also known as dichroic mirrors or dichroic mirrors. And placed at an angle of 45 ° to the optical path of the microscope. This filter reflects one color of light (excitation light) and transmits another color of light (emitted light), the reflectivity of the excitation light is greater than 90% and the transmittance of the emitted light is greater than 90%. The impervious portion of the spectrum is reflected rather than absorbed. Filter in the transmitted light and reflected light color complement each other, and thus also known as dichroic filters.

Our fluorescence filter are designed for fluorescence imaging applications, with durability in mind and high-performance optical specifications in manufacturing. The filter substrate is made of quartz, which can achieve 1/10 lambda surface accuracy, while the thermal expansion coefficient of quartz is relatively small, can obtain higher image quality.

Dichroic optical filters consist of thin film dielectric coatings on glass and exhibit sharp transitions between transmitted and reflected wavelengths. Dichroic filters are similar to traditional interference filters but differentiate themselves by reflecting all unwanted wavelengths. Consequently our dichroic range also offers minimal absorbance characteristics.

Our dichroic filters are available in longpass, shortpass, bandpass, bandblocking and colour correction types over a range of wavelengths. Dichroic shortpass and longpass filters can also act as hot and cold mirrors respectively.

Dichroic filters can divide natural light from a certain wavelength into two parts, one of which passes through, and the other is reflected or absorbed. Filters that allow longer wavelengths of light to pass through are referred to as long wave pass filters, and filters that allow shorter wavelengths of light to pass through are referred to as short wave pass filters.

The desired spectral range can be achieved by using different dichroic filters.

Telecentric Lenses(2023年10月06日)

hypoptics — 2023-09-22T15:20:17+0900

http://www.hypoptics.com/lens-assembly/telecentric-lenses.html

In many machine-vision systems, such as those used in semiconductor inspection, precise repeatable measurements must be made consistently. To ensure this occurs, system developers must turn to more expensive optical systems based on telecentric lens with which to image these parts.
Many of the reasons for choosing telecentric lenses emerge from the limitations of more conventional lens systems. For example, should an object move even slightly within the depth of field of a conventional lens system, there will be an associated magnification change. In the past, magnification changes due to object displacement were calibrated by means of an additional camera or a depth sensor tracking the distance between the lens and the object. The use of a telecentric lens can substantially reduce or even eliminate such magnification changes and therefore remove the need for any additional camera and preprocessing of the image data that may otherwise be required to correct for any magnification errors.

Perspective or parallax errors can also be eliminated by the use of telecentric lenses. In conventional optical systems, closer objects appear relatively larger than those further away because the magnification of an object changes with its distance from the lens. However, telecentric lenses optically correct for this parallax error so that objects remain the same perceived size independent of a specific distance from lens.

Telecentric lens can solve above problems effectively in a specific working distance. Telecentric lens has same magnification which isn't change with DoF after focalization. Telecentric lens can provide superior image quality with low distortion and no parallax, so it can be used in high precise measurement and the detection of the work piece’s defect.

We provide telecentric optical system, telecentric system, telecentric lens depth of field, telecentric lens design, hyp design, etc. For more information, please feel free to contact us!

Surveillance Lenses

Our CCTV lens for camera come in many forms, including fixed focal-manual iris, fixed iris-manual focus, varifocal, motorized zoom lens options, and pinhole lenses. Each security camera lens we offer provides unique functionality and is designed for different surveillance applications. Auto-iris lenses are designed for outdoor use, or any applications with variable lighting conditions. Fixed lenses provide fixed focal lengths from super wide angle to telephoto depending on the camera format and intended application. Varifocal lenses are designed to meet a variety of applications, providing the flexibility to adjust between different focal lengths with a single lens.

100m, 500m or even 1km away objects can also be clearly displayed on the monitor. The decisive factor in this issue, in general, is the focal length of the lens, the longer the focal length, "see" the farther away, but at the same time the field of view is smaller, the results narrowed the viewing range.

In order to be able to more clearly detect the target within the scope of monitoring and automatic tracking, the general requirements of the target in the CCD target surface occupies at least three lines of television lines. To be able to distinguish the characters, the general should ask the person's facial imaging in the 356mm (14in) monitor accounted for more than 12.7mm (0.5in).

In practical applications, users often ask the camera to see how far objects or the camera can see how wide the scene and other issues, which in fact should be selected by the focal length of the lens to decide, in addition to the The resolution of the selected camera and the resolution of the monitor.

The focal length of the optical system is the distance from the main point of the optical group to the focal point. And the focal length of the lens is actually a combination of the composition of the focal length of the lens group, which determines the size of the image taken with different focal length of the lens on the same location of the camera, with long focal length camera lens intake of the scene size Large, and vice versa, with a short focal length camera lens intake of the scene size is small.

Projection Lenses(2023年10月03日)

hypoptics — 2023-09-22T15:17:56+0900

http://www.hypoptics.com/lens-assembly/projection-lenses.html

Projection lens and photographic lens is a pair of opposite lenses, the camera lens is used to image the outside world to the CCD or COMS in the digital format, on the other hand the projection lens design to digital format images projected onto the screen.

From the optical design point of view of these two lenses are no different, because the optical path is reversible. However, they still have some differences. First, the photographic lens is generally iris adjustable diaphragm, which control in the photography industry is known as the aperture. tv lenses generally in order to maximize the output illumination, aperture stop is not adjustable.

Second, the projector lens is generally fixed focus lens, even zoom lens projectors, the zoom ratio is generally not greater than 2, consumer digital camera zoom ratio are normally more than 3, only the SLR digital camera with fixed focus Lens or a lens with a zoom ratio less than 3.

Third, the lens of different caliber, projection lens diameter is generally much larger than the camera lens.

At Hyperion Optics we develop projection lenses as following:

Short focus (ultra-short focal length) lens, which is used to project large-screen short-range
Medium focal length lens for normal distance projection
Telephoto (super telephoto) lens, for long-range projection of small screen

In addition to that there is a ball screen lens, it is a single lens shot surface

We can design and produce high performance projection lens, the maximum resolution of up to 4K, projection ratio can reach 0.8: 1, which means that the distance of one meter projection of 60-inch screen.

The following table shows the relationship between the projection ratio and the focal length

Now, with the increasing proportion of widescreen video, deformation projection lens has gradually begun to penetrate into the market. Compared to traditional projection lens + deformation lens, the deformation projection lens structure is more compact, better image quality, lower prices.

We have a wealth of experience in design and manufacturing, and we can make performance / price balance designs based on different chip sizes, resolutions, and projection ratios.

Ge Lenses
In the range of 2-12 μm, germanium is the most commonly used material for the production of spherical lenses and germanium ir windows for high efficiency infrared in the imaging system. Germanium has a high refractive index (about 4.0 through 2-14μm band), usually do not need to be modified due to its low chromatic aberration in low power imaging systems.

Germanium optical performance is severely affected by temperature; the transmission rate decreases with the increase of temperature, most applications with Germanium elements involved can only be applied below 100 degrees Celsius. Designers also need to pay attention for certain weight constraints in system design with a density of germanium (5.33 g/cm3). Germanium is mainly used in the thermal imaging system and infrared (FLIR) field.

It is critical that the surface of the material has a promising finish and good transmittance. Hyperion Optics provides 40-20 surface quality Ge lenses as factory standard products, with up to 1/4 lambda in surface accuracy.

Telecentric Lenses
In many machine-vision systems, such as those used in semiconductor inspection, precise repeatable measurements must be made consistently. To ensure this occurs, system developers must turn to more expensive optical systems based on telecentric lenses with which to image these parts.

Many of the reasons for choosing telecentric lenses emerge from the limitations of more conventional lens systems. For example, should an object move even slightly within the depth of field of a conventional lens system, there will be an associated magnification change. In the past, magnification changes due to object displacement were calibrated by means of an additional camera or a depth sensor tracking the distance between the lens and the object. The use of a telecentric lens can substantially reduce or even eliminate such magnification changes and therefore remove the need for any additional camera and preprocessing of the image data that may otherwise be required to correct for any magnification errors.

Perspective or parallax errors can also be eliminated by the use of telecentric lenses. In conventional telecentric optical system , closer objects appear relatively larger than those further away because the magnification of an object changes with its distance from the lens. However, telecentric lenses optically correct for this parallax error so that objects remain the same perceived size independent of a specific distance from lens.

Telecentric lens design can solve above problems effectively in a specific working distance. Telecentric lens has same magnification which isn't change with DoF after focalization. Telecentric lens can provide superior image quality with low distortion and no parallax, so it can be used in high precise measurement and the detection of the work piece’s defect.

Projection Lenses
Projection lens and photographic lens is a pair of opposite lenses, the camera lens is used to image the outside world to the CCD or COMS in the digital format, on the other hand the projection lens to digital format images projected onto the screen.

From the optical design point of view of these two lenses are no different, because the optical path is reversible. However, they still have some differences. First, the photographic lens is generally iris adjustable diaphragm, which control in the photography industry is known as the aperture. Projection lens generally in order to maximize the output illumination, aperture stop is not adjustable.

Third, the lens of different caliber, projection lens diameter is generally much larger than the camera lens.

What is the Transmittance of Achromatic Lens?(2021年05月14日)

hypoptics — 2021-05-08T12:47:55+0900

http://www.hypoptics.com/components/achromatic-lenses/

At present, there are many manufacturers producing achromatic lenses in China. Although the products of each company are called achromatic lenses, the raw materials and technology are quite different, which results in the different transmittance of achromatic lenses in the market. So how much light transmittance can achromatic glue lens achieve?

In fact, achromatic lens refers to a kind of photoelectric glass which combines liquid crystal dimming film and glass clip glue and has the effect of "electrifying transparency, power off and grinding opacity".

When purchasing achromatic plywood lens, one of the most concerned parameters of customers is the transmittance. The higher the transmittance, the better the product. The transmittance of the achromatic lens is mainly affected by the following three aspects: glass original film, film clip and dimming film.

First of all, glass. Glass is mainly divided into white glass and super white glass. Plain white glass contains iron oxide, manganese oxide and other metal oxides. It looks green. Generally, its transmittance rate is 82%~84%. Ultra-white glass contains very low metal oxides. It looks translucent and elegant. Generally, its transmittance is 89%~91%. But at present, the transparency of ultra-white glass produced by the most advanced equipment is only 93%.

Then let's talk about film. There are two kinds of film for the clamping of achromatic glue lens: EVA and PVB. The transmittance of better transparent film can reach more than 90%. The transmittance of films with different qualities and colors is quite different, which is not to be discussed here.

The transmittance of dimming film is the most important factor affecting the transmittance of achromatic lens. There are domestic and imported dimming films. The transmittance of domestic films is generally between 73% and 83%. The transmittance of imported films is generally higher than that of domestic films. The transmittance can reach 85% or higher, but the price is also rising.

The Benefit of Aspheric Lens-Spherical Aberration Correction(2021年05月13日)

hypoptics — 2021-05-08T12:47:22+0900

http://www.hypoptics.com/components/achromatic-lenses/

The most significant advantage of aspheric lens is that it can correct spherical aberration. Spherical aberration is caused by focusing or aligning light with a spherical surface. Therefore, in other words, all spherical surfaces, whether or not there are any measurement errors or manufacturing errors, will have spherical aberrations. Therefore, they all need a non-spherical or aspherical surface to correct it. By adjusting the conical constant and non-spherical coefficient, any non-spherical lens can be optimized to minimize aberration. Spherical lens is a lens with significant spherical aberration, not a spherical lens with almost no spherical aberration. The spherical aberration in a spherical lens will focus the incident light at many different fixed points, resulting in blurred images. In aspheric lenses, all the different light rays focus on the same fixed point, thus producing images with less blur and better quality.

In order to better understand the difference of focusing performance between aspherical lens and spherical lens, the point or blur of light produced by two equal lenses (f/1 lens) with a diameter of 25 mm and a focal length of 25 mm, parallel and monochrome light (wavelength 587.6 nm) on the comparative axis (object angle of 0 degree) and off-axis (object angle of 0.5 degree and 1.0 degree) were observed. It is known that the spot size of aspheric lens is several orders of magnitude smaller than that of spherical lens.

Additional Benefits of Aspheric Lenses(2021年05月12日)

hypoptics — 2021-05-08T12:46:49+0900

http://www.hypoptics.com/components/achromatic-lenses/

Although there are many different techniques for correcting aberrations caused by spherical surfaces on the market, these other techniques have far less imaging performance and flexibility than aspheric lenses can provide. Another widely used technique involves adding lenses by "shrinking" them. Although this can improve the image quality, it will also reduce the light flux in the system. Therefore, there is a trade-off between the two. On the other hand, when using aspheric lens, its additional aberration correction supports users to achieve high luminous flux (low f/ and high numerical aperture) system design while maintaining good image quality. Image degradation caused by higher luminous flux design is sustainable because a slightly reduced image quality still provides better performance than a spherical system.
System advantage
Aspheric lenses allow optical element designers to use fewer optical elements than traditional spherical elements to correct aberrations, because the former provides more aberration correction for them than the latter uses multiple surfaces to provide aberration correction. For example, a zoom lens with ten or more lens elements can replace five or six spherical lenses with one or two aspherical lenses, which can achieve the same or higher optical effects, reduce production costs and reduce the size of the system. Optical systems with more optical elements may have a negative impact on optical and mechanical parameters, resulting in more expensive mechanical tolerances, additional calibration steps, and more requirements for antireflective coatings.

All of these results will ultimately reduce the overall practicability of the system, because users will have to constantly add support components to it. Therefore, adding aspheric lens to the system (although the price of aspheric lens is more expensive than the same single lens and double lens), will actually reduce the cost of your overall system design.

What Parameters should be Paid Attention to in Aspheric Lens Selection?(2021年05月11日)

hypoptics — 2021-05-08T12:46:18+0900

http://www.hypoptics.com/components/achromatic-lenses/

1. Designed wavelength: the wavelength that makes aspheric lens achieve the best effect. Aspheric lenses can also be used at other wavelengths.

2. Numerical aperture (NA): Measure the maximum angle of light that a lens can accept. NA = sin (Φ)

3. Pass-through aperture: According to the design, the maximum diameter of light energy passing through the surface. It is smaller than the actual spherical diameter, i. e. physical aperture (PA).

4. Effective Focal Length (EFL): The distance between the main plane and the focus. The normal tolerance is (±1%).

5. Amplification factor: the ratio of image size to object size. Calibration lenses are not limited.

6. RMS WFE: Measurement value of chromatic aberration (error) in lens. Diffraction limitation means that due to the diffraction, the lens conforms to the theoretical limitation (the highest level of operation that can be achieved in accordance with the physical laws).

7. Outer diameter: the diameter of the outer cylinder of the lens, the standard tolerance is (±0.015 mm).

8. Working distance (WD): Also known as Back Focal Length (BFL), which represents the distance from the back of the lens to the focus.

9. Central thickness: Thickness in the Axis of the Lens.

Aspheric lens is superior to spherical lens.
1. A non-spherical lens can replace the combination of multiple spherical lenses, thus reducing the number of parts.
2. The fewer lenses in the system means fewer assemblies and adjustments, which saves labor time.
3. The smaller number of lenses in the system means that light will illuminate less lens surface, reduce backlighting and improve the optical transmission in the whole system.
Less lenses mean smaller and lighter systems.

Different Advantages of Each Aspheric Lens Type(2021年05月10日)

hypoptics — 2021-05-08T12:45:45+0900

http://www.hypoptics.com/components/achromatic-lenses/

Since the lens performance required for all applications is different, it is very important to choose an appropriate aspheric lens. Key factors to consider include your project schedule, overall performance requirements, budget constraints, and projected quantities.

Spot lenses are available immediately, so many applications may be satisfied with the use of off-the-shelf aspherical lenses. However, these standard aspheric lenses can be quickly and easily modified by antireflective film or can be reduced in size to meet the requirements of standard products. If spot products are insufficient to meet the demand, customized aspheric lenses can be used for prototyping, pre-fabrication or mass manufacturing applications.
Here are the advantages of different types of aspherical lenses
1. Precision glass forming aspheric lens
It is very suitable for high-volume production, because it can produce a large number of lenses quickly, and the tool maintenance cost is low.
2. Precision polished aspheric lens
It is very suitable for small batch production, because the delivery time is short, only a small number of special tools and settings are needed.
3. Hybrid aspheric lens
It is very suitable for multispectral applications because spherical aberration and achromatic aberration correction can be provided simultaneously.

4. Plastic moulded aspheric lens
It is very suitable for high-volume production and is a low-cost, light-weight alternative product for aspheric lens.

Advantages and Disadvantages of Aspherical Lenses(2021年05月09日)

hypoptics — 2021-05-08T12:45:12+0900

http://www.hypoptics.com/components/achromatic-lenses/

The surface radian of aspherical lens is different from that of ordinary spherical lens. In order to pursue the thinness of the lens, it needs to change the surface of the lens. Aspheric lens should be designed as flat as possible. However, the optical properties of flattened lenses, even if they are designed with aspheric surfaces, will decline rapidly. At the same time, the lens is lighter, thinner and flatter, and it still maintains excellent impact resistance, so that the wearer can use it safely.
Advantages of aspherical lenses:
1. Optical advantages: reduce the aberration of the lens and make the vision clearer.
2. Clear images can also be obtained at high luminosity: Although the spherical point focus lens is designed by the best base arc, the luminosity beyond + 7.00D-22.00D is not within the Cherning ellipse, and the aberration can not be eliminated. Only aspheric design can achieve better quality.
3. It can make the lens flatter, thinner and more beautiful. The higher the lenticity of spherical lens, the worse the appearance. Aspheric lens can be designed with flat base arc, which not only makes the appearance beautiful, but also reduces the peripheral magnification. Let others see the wearer's eyes, will not change a lot in size.
Defects of aspherical lenses:
1. Aspheric lens has a relatively small light area. When the eyeball rotates around, it will blur a little when looking at the outside through the lens edge, that is, the visual range of the line of sight becomes smaller.

2. Human's eyeball is spherical. The eyeball rotates to the edge. Through aspheric lens, the object near the eye appears protruding.

How to Design and Manufacture Aspherical Lens?(2021年05月08日)

hypoptics — 2021-05-08T12:44:35+0900

http://www.hypoptics.com/components/achromatic-lenses/

Aspheric fabrication is different from traditional spherical fabrication. In traditional spherical manufacturing, the surface is defined by a single radius of curvature. Curvature can be ground and polished using large tools. This polishing tool smoothes the relative curvature of the finished product surface into the desired shape by oscillating and polishing the curvature center of the medium such as slurry.
1. Selection of aspherical lens materials
CNC and MRF optical glass and crystal materials; in addition, plastics can be chosen. Diamond turning is suitable for crystals, plastics and metals. Diamond turning works well for infrared optical materials and is inherently insensitive to higher surface roughness. Precision glass forming is limited, transition temperature < 500 degree C and thermal expansion coefficient of glasses are low enough, in a very limited choice of glasses. Choices have increased dramatically over the past decade, but still account for only a small fraction of all available optical glasses.

The glass softening temperature is lowered to room temperature in the forming process. In a short time, the glass is annealed and its index is lowered. This decline means that finished lenses will not have the same index as the glass catalogue specification. When designing precision glass moulding, users need to consider the low index in their models.

2. Design of curvature radius of aspherical lens
Compared with spherical lenses, aspherical lenses do not have a single radius of curvature. The edge change of the central part of the radius of local curvature. This leads to the possibility that the local radius of curvature can change the different points of its symbols from convex to concave on the surface, as shown in Figure 3. The place where the point occurs is called a turning point, which may lead to mold and measurement problems. In Zemax software, the cross section of the surface curvature can be used to check the local curvature radius of the surface.

Round Concave Mirriors(2020年08月06日)

hypoptics — 2020-08-03T16:18:30+0900

http://www.hypoptics.com/about-us/resources/round-concave-mirriors.html

Round concave mirrors are catoptric imaging. Mirrors( including convex) are reflecting back for imaging rather than get through the light, ray of light follows the law of reflection, that is what we called convergence. They always gather the light that shoot to the surface, ray of light that is entered parallelly will be focus on the spot again, ray of light is reflected from different angles because of different directions of surface normal. Round concave mirrors can not only focus parallel ray of light on the spot but also reflect parallel light from spot.

The diagram of a round concave mirror shows focus, focal length, centre of curvature and principal axis. Concave mirrors or gathering mirrors will deflect reflected ray of light. Concave mirrors will have different images because of the different distance between objects and mirrors, which is different from convex mirrors.

Round concave mirrors don’t have chromatic aberration because they are catoptric imaging, this advantage is can’t be compared with any lens. The resolution ratio is in direct proportion to the clear aperture of objective, it is difficult for the production of large aperture lens while concave mirrors that made according to reflection principal are easier. Therefore, round concave mirrors are always used for producing telescope.

Laser Optics - White Light Laser and its Application(2020年08月06日)

hypoptics — 2020-08-03T16:18:09+0900

http://www.hypoptics.com/about-us/resources/laser-optics---white-light-laser-and-application.html

The existing laser technology has always had a short board, which can only emit light of a single wavelength or narrow band. How to expand the frequency of the laser forming ultra broadband, super straight, ultraviolet, visible and infrared wavelengths of coherent white light laser, is still a human unfulfilled dream, it is a worldwide problem of science and technology. This is because the laser optics is composed of optical resonator, gain medium and pump source. The wavelength of the laser is determined by the energy level structure of the atoms, molecules or ions in the gain substance.

Because the natural laser crystal material has a great limitation on the gain frequency range and gain bandwidth, the laser can't produce any wavelength of laser.
Will the perfect white laser be created? What changes and developments could it bring to the application of lasers?

1. The sun light

It is known to all that all things grow by the sun, and the sunlight brings light and heat to the earth. The familiar sunlight is a kind of white light, and its spectrum covers ultraviolet - visible - near infrared - mid-infrared bands, as shown in figure 1, In the visible light band (400-700 nm), the radiation energy is strongest, covering seven colors of red, orange, yellow, green and blue, and continuous distribution and transition in the spectrum. Because the sun is white, rainbows are often seen in the sky after rain, or the sunlight passes through a glass prism through seven colors of light (figure 2). This is a common experience in everyday life.

One of the things that people are less familiar with is that sunlight is a completely incoherent light. In terms of spatial coherence, the sunlight cannot be straight and highly divergent. In terms of temporal coherence, there is no phase correlation and locking between different colors of sunlight. So sunlight can only be used to generate energy for heating, water heaters, solar cells and so on.

But the use of modern science and technology, such as the use of sunlight to transmit information, seems to be out of the question.

laser

The spectral distribution of sunlight. The spectrum of solar radiation including the sun itself, the spectrum of sunlight entering the earth, and the spectrum of sunlight reaching the sea level due to the absorption of atmospheric water and carbon dioxide.

2. The advantages of light and its application

White light laser light source, short wave laser light sources and continuous laser light compared with the ordinary white light, such as sunlight, incandescent lamp, white LED lamp, etc.), it has the advantages of high brightness, high peak power, wide frequency range etc. In the fields of scientific research, defense military, lighting, communication technology, information technology, industrial production, biomedicine, environmental detection, etc.it got a lot of attention.

White light, as a kind of new laser light source, it has a variety of advantages of good directionality, high energy density, super continuous spectrum, great bandwidth, the center of the flexible wavelength, high degree of coherence time and space. This will greatly expand the function and application scope of laser technology. The white light laser or the solar laser is the completely coherent light, not only the height of the laser beam, but also the very small region. Different color between amplitude and phase locking completely, by regulating the amplitude and phase, it can change the time of laser pulse shape follow one's inclinationsly, and produce very short pulse width (femtosecond and the femtosecond laser pulses. Such a solar laser will have the potential to realize the focus and convergence of light energy in space and time. It releases energy in small areas and very short periods of time to form extremely high instantaneous power density.

Is a Aspherical Camera Lens Better than a Spherical Lens?(2020年08月05日)

hypoptics — 2020-08-03T16:17:37+0900

http://www.hypoptics.com/about-us/resources/is-aspherical-camera-lens-better-than-spherical.html

Do you know the difference between spherical and aspheric lenses?

The aspheric
When it comes to the lens, you have to mention the aspherical lens. In many people's understanding, the asperical lens is a symbol of high level, and the advanced lens is almost all aspherical lenses.

Let's start with what is called a aspherical camera lens. The aspherical lens is contained in the camera lens, aspheric is often calculated according to the surface, some aspherical lens side, the other is not, or both sides is spherical, and so on.

In general, a lens with two or more aspherical lenses is a very advanced lens. So, is the aspheric surface a very difficult technique?
We can look at it from the other side.

Now, in terms of glasses, the aspheric surface is also very widely used, and in fact, it is no more expensive than the spherical lens. For numerical control grinders, the wave surface can also be made.
Clearly, many people's understanding of the aspheric surface is still stuck in the leica 501.2 myth, which itself has long since been broken.

Of course, many people would still use the so-called "grinding aspheric", but don't say what grind the aspheric surface. I believe that for many people, it's impossible to tell whether a picture is not a spherical lens.

Is the aspheric surface necessarily good?

Even if it's a cock shot, it's impossible for each lens to be aspherical, the aspheric lens is actually a supporting role in the lens, not the main character, the main corrective, the correction function, after the use of aspherical lenses, the image of the edge of the image will be solved well and the picture will be more average.

So, is it a good thing to have an aspheric surface? From the current situation, the use of aspheric surface technology has become the standard configuration, especially the high technology index lens, for example, large aperture wide-angle zoom lens, it is difficult to guarantee the quality of the picture without the aspheric surface.

But in terms of our film fans, the aspherical lens we can use is relatively limited, after all, we use the camera mainly concentrated in the last century 60-90s, until the 90s, aspherical lens or less. Here we're talking about 135, and less in 120. We have seen that CAI has built so many classic Hau shots, such as the 384.5 on SWC, and there is no aspherical lens.

In a series of SLR lenses designed by Mr. CAI for nikon, many of them have no aspheric surfaces. But it doesn't prevent these lenses from being a good shot, like chase 50, 1.4 SLR, and the picture is average. Aspherical Camera Lens Better than a spherical lens camera is ture.

Diamond has some remarkable properties: for example, its refractive index is 2.4, which is very high, and can be made into thinner optical components for optical systems with the same optical power. Their thermal conductivity is 2000 W/m*K, 1400 times higher than that of optical glass.

So far, polycrystalline diamond substrates have only been used as light windows for carbon dioxide lasers. Due to impurities and defects, they absorb and scatter laser radiation at the emission wavelength of 1 micron, so they are not suitable for fiber lasers. Although single crystal diamonds do not have this problem, they are difficult to manufacture. Over the years, the German Fraunhofer Institute for Applied Solid State Physics (IAF) has been devoted to the production of single crystal diamond. The continuous vapor deposition (CVD) reaction chamber developed in IAF has stable plasma conditions and it can produce a substrate with a thickness of several millimeters.

It can simultaneously process 60 diamonds at most. At a rate of up to 30 microns per hour, the reaction chamber can produce an optical element with an aperture of about 10 millimeters.

The lenses made of these synthetic single crystal diamonds have low absorptivity and low birefringence. At present, some samples coated with antireflection film have been provided and used in fiber laser cutting head. "We have optimized a complete hyperion laser optical system for diamond lenses for the first time, and the weight of the cutting head has been reduced by 90%," said Martin Traub of the Fraunhof Institute of laser technology".

The lens with a diameter of 7mm has passed the test of 2 kW laser power, without any problems. Now, partners have built a cutting test system using 1kW fiber lasers. Water cooling and protective gas supply are integrated in the cutting head. Process monitoring has not been planned. Currently, compact cutting heads is in process of testing for the first time.

A new optical system will significantly enhance the flexibility of laser cutting. The small size enables the system to process inaccessible areas, while the low weight is beneficial to the high dynamic motion in the 3D process.

The core problem of underwater activity of divers is that humans cannot ingest oxygen from water, therefore, it is necessary to carry gas cylinders or to supply gas from the water surface, and the breathing problem has become one of the most complicated technologies in diving technology. But the water actually dissolves a certain amount of oxygen, fish is through the gills to absorb oxygen from the water to maintain life. In theory, if you can master the rapid uptake of oxygen from water, then humans do not need to carry gas in the underwater activities. But keeping breathing for a long time under water has always been considered unthinkable and impossible, scuba diving can only continue to be carried out underwater by carrying air or by piping. Because fish can absorb oxygen from the water by their gills, humans and mammals don't have gills, and they can't use oxygen in the water to support life.

Do you know how fish breathe underwater？
Let the human fish breathe oxygen in the water for a long time to survive in the water, it sounds like science fiction, and Danish scientists have recently been able to get oxygen permanently underwater, which is a step toward that goal. It's because of the kind of crystal material they developed, this synthetic material is named Neptune crystal AquamanCrystal. This synthetic material can continuously ingest oxygen from air and water without any other means. The oxygen absorbed by the crystal can be released as long as it is heated slightly or exposed to low oxygen pressure. At present, it is difficult to produce this kind of synthetic crystal material in large quantities.

The implications of this finding are profound, says Christina Mackenzie, a professor at the university of Denmark, who led the research. She told the science daily: "this material can absorb oxygen from the air. Patients with respiratory dysfunction need daily oxygen, the technology will allow patients to get rid of heavy oxygen tanks. Divers may also use the technology in the future to carry a small amount of this crystal grain. The diver breathes the material into the water to absorb oxygen that is dissolved in water, so there is no need to carry gas cylinders or supply the gas from the water. So they named the crystal AquamanCrystal.

Neptune crystals have a spongy composition that absorbs oxygen.

Neptune crystals absorb oxygen and rely on cobalt ions. This is very similar to the ability of hemoglobin to absorb oxygen. Because oxygen is difficult to dissolve in water and blood, all living things on earth use metal ions to combine and transport oxygen. The hemoglobin in the blood of people and many animals depends on the combination of iron and oxygen. Myoglobin, the myoglobin in muscle cells, is also a similar molecule. Animals such as crabs and spiders rely on copper ions to combine and transport oxygen. The ability of metal ions to absorb oxygen is huge. So it's not surprising that this crystal glass has a powerful ability to absorb oxygen.

1. Achromatic doublet lens is a kind of common lens. It consists of several groups of positive and negative cemented lenses with different radius of curved surface. It can only correct the axial chromatic aberration of red and blue light in spectral line. At the same time, the spherical aberration on the axis and the coma aberration on the paraxial point are corrected. This kind of lens can not eliminate the second-order spectrum, only the spherical aberration and chromatic aberration in the yellow and green wave regions are corrected. The spherical aberration and chromatic aberration of the remaining chromatic aberration and other wave areas can not be eliminated, and the image field bending is still very large, that is to say, only the clear image in the middle of the field of view can be obtained. It is advisable to use yellow-green light as illumination source or insert yellow-green filter in the optical path. This kind of lens is simple, economical and practical. It is often used in conjunction with correction eyepiece and is widely used in medium and low power microscopes. In black-and-white photography, green filters can be used to reduce the residual axial chromatic aberration and obtain good contrast photographs.

2. Complex achromatic doublet lens is composed of several groups of advanced lenses made of special optical glass and fluorite. The axial chromatic aberration is corrected by red, blue and yellow light, and the secondary spectrum is eliminated. Therefore, the image quality is good, but it is difficult to process and calibrate many lenses. The correction of chromatic aberration is in all wavebands of visible light. If blue or yellow filters are added, the effect will be better. It is the best objective in the microscope. It has good correction for spherical aberration and chromatic aberration. It is suitable for high magnification. However, it still needs to be used with compensating eyepiece to eliminate residual chromatic aberration.

3. Planar achromatic doublet lens is a complex optical structure composed of multiple lenses, which can correcting astigmatism and image field bending well, and make the whole field of view clear. It is suitable for microphotography. The correction of spherical aberration and chromatic aberration of the objective is still limited to the yellow-green wave region, and there is still residual chromatic aberration.

4. Planar achromatic doublet lens has the same degree of aberration correction as complex achromatic objective lens except for further image field bending correction, which makes the image clear and flat. But the structure is complex and difficult to manufacture.

Basic knowledge of aspheric lens technology(2020年08月03日)

1、Technical principle

The curvature radius of the aspheric lens changes with the center axis. It can be used to improve optical quality, reduce the number of optical components and reduce design costs. Compared with spherical lens, aspheric lens has unique advantages, so it has been widely used in optical instrument, image and photoelectron industry, such as digital camera, CD player and high end micro instrument.

2、Comparative advantage

a, Spherical aberration calibration

The most remarkable advantage of aspheric lenses in replacing spherical lenses is that they can correct the spherical aberration caused by spherical lenses in collimating and focusing systems. By adjusting the surface constant and the aspheric coefficient, the aspheric lens can eliminate spherical aberration to the maximum extent.Aspheric lenses (rays converge to the same point and provides optical quality) basically eliminate spherical aberrations produced by spherical lenses (rays converge to different points and leads to blurred imaging).

Three spherical lenses are used to increase the effective focal length, which can be used to eliminate spherical aberration. However, a aspheric lens (high numerical aperture, short focal length) can be realized, and it can simplify the system design and provide the light transmittance.

b, System advantages

The aspheric lens simplifies the elements involved in optical engineers to improve the optical quality and improves the stability of the system.For example, in zoom systems, 10 or more lenses are normally used (additional: high mechanical tolerances, additional assembly procedures, and the improvement of antireflection coating). However, one or two aspheric lenses can achieve similar or better optical qualities. This reduces the system size, increases the cost rate and reduces the overall cost of the system.

3、Moulding techniques

a, Moulding of precision glass

The molding of precision glass is to make the glass material heated to high temperature and become plastic, and then molded by aspheric mold, and finally gradually cooled to room temperature.At present, the molding of precision glass is not suitable for aspheric lens with diameter greater than 10mm. However, new tools, optical glass and metrology process are driving the development of the technology. Although precision glass molding at the beginning of the hyp design has high cost (high precision mold development), but after the molding, the production of high-quality products can be split off the pre development costs. It is especially suitable for the needs of mass production.

b, Forming of precision polishing

Lapping and polishing are generally applicable to the production of monolithic aspheric lenses at one time. With the improvement of technology, the accuracy is higher and higher.The most remarkable thing is that precise polishing is controlled by computers and automatically adjusted to optimize parameters.If higher quality polishing is required, magnetorheological finishing (magneto-rheological finishing) will be adopted. Compared with standard polishing, magnetorheological finishing has higher performance and shorter time.Precision polishing molding technology need professional equipment. It is currently the first choice of sample production and small batch sample.

c, Hybrid molding technology

The hybrid molding is a spherical aspheric lens with a spherical lens as the substrate, which is cast on the surface of the spherical lens through an aspherical mould and cured by a layer of high polymer with UV light.Mixed forming is generally used the achromatic spherical lens as the base, and then a layer of aspheric surface is cast on the surface to eliminate chromatic aberration and spherical aberration simultaneously.Figure 7 is the manufacturing process of the hybrid aspheric lens. The hybrid aspherical lens is suitable for large scale manufacturing with additional characteristics (eliminating chromatic aberration and spherical aberration) .

d, Injection molding

In addition to glass aspherical lenses, there are plastic aspheric lenses.Plastic molding is the injection of molten plastics into aspherical molds.Compared with glass, the thermal stability and compressive resistance of plastics are poor. It requires special treatment to obtain similar aspherical lenses. However, the plastic aspheric lens is characterized by its low cost, light weight and easy molding. It is widely used in the fields of moderate optical quality, insensitive to thermal stability and little pressure resistance.

4、Basis of choice

All kinds of aspheric lenses have their own relative advantages. Therefore, it is very important to choose the right products for different applications. The main considerations include: batch, quality and cost.
