What is the Difference Between Spherical and Aspheric Lenses?(2024年04月23日)

https://www.ecoptik.net/what-is-the-difference-between-spherical-and-aspheric-lenses.html

What is a spherical lens? What is an aspheric cylindrical lens? What is the difference between spherical and aspheric lenses? Why are aspheric lenses recommended? Let's talk about the difference between the two.

The spherical lenses have a spherical surface, and the radius of curvature of the entire lens is the same. On the contrary, the surface of an aspheric cylinder lens is more complicated, and the curvature gradually changes from the center to the edge. These design differences can reduce the number of elements in the assembly and result in thinner and lighter lenses.

The surface of the spherical lens looks like a part of a spherical or cylindrical surface.

The curve is the same across the entire surface. If you draw a straight line to follow the curve, it will form a circle. Because the design is simple, the spherical lens design is usually cheaper.

The surface of an aspheric lens must not be part of a sphere or cylinder. The curve of some parts of the lens surface changes to better focus the light. This change in the surface corrects various aberrations.

1. What is a spherical lens?
Imagine a transparent sphere with a circle in front of us. The surface of a sphere is a surface called a sphere. The spherical lens only means that one surface of the sphere is selected as the lens.

2. What is an aspheric lens?
Literally, it is easy to understand, this means that the lens is not spherical.

3. Aspherical lenses in spectacle lenses
In appearance, spherical lenses are "big belly", but aspheric lenses are relatively flat, so from an aesthetic point of view, aspheric lenses will look better. There are many aspheric lenses advantages. For example, aspherical lenses are precisely designed and optimized for the combination of lens powers, so they are thinner and more resistant to collisions than spherical lenses. Therefore, people with higher power usually wear aspheric lenses.

When you look at the world through the lens, the difference will be more obvious. When looking around the spherical lens, distortion occurs. Due to the aspherical lens design, the aspheric lens can minimize the difference between the edges of the lens. Seeing objects is more natural, less deformed, and more real.

4. Aspheric lenses are so good, why do people choose spherical lenses?
For friends with mild myopia, the spherical and aspheric lenses are almost the same, there will be no aberration problems, and the lens thickness is similar. Considering the price factor, you can choose spherical lenses.

In addition, for a small number of people who are particularly sensitive to colors, such as wearing aspherical lenses will feel the rainbow phenomenon, you can try to replace the spherical lens.

What is a Double Concave Lens?(2024年04月22日)

ecoptik — 2024-04-17T15:54:13+0900

https://www.ecoptik.net/what-is-a-double-concave-lens.html

1. Introduction to double concave lens
A double concave lens is also called a negative spherical lens. The middle of the lens is thin, the edge is thick, and it is concave, so it is also called a concave lens, which has a divergent effect on light.

The imaging law of the concave lens is: when the object is a real object, it becomes an upright, reduced virtual image, and the image and the object are on the same side of the lens. The concave lens has a divergent effect on the light, so the lens is also called a divergent lens, a negative spherical lens.

2. Features of biconcave lens:
A double concave lens is concave on both sides and has the same radius of curvature. A double concave lens with a negative focal length is usually used for beam collimation, increasing (decreasing) the focal length or enlarging (shrink) the image.

The double concave lens has a negative focal length and is often used in imaging or beam collimation applications. The coated lens is also widely used in visible light and near-infrared applications.

Conventional lens sizes are: Φ12.7mm, Φ25.4mm, Φ50.8mm, and customized double convex lenses can be produced according to customer project requirements.

https://www.ecoptik.net/video/polarization-beamsplitter-cube-pbs.html

Polarizing Cube Beamsplitters Introduction
Polarization beamsplitter cube split randomly polarized beams into two orthog-onal, linearly, polarized components-S-polarized ligh is reflected at a 90°.

Angle while P-polarized light is transmitted. Each beamsplitter consists of a pair of precision high tolerance right angleprism cemented together with a dielectric coating on the hypotenuse of one of prism.

The coatings have been designed to hold both the S-and P-polarization components to the same ratio of reflection-to-transmission over aspecific laser wavelength region.

This means that they will not change the state of polarization of the incident beam. The low polarization dependence of the metallic-dielec-tric coating allows the transmission and reflection for S-and P-polarization states to be within 6% of each other. All entrance and exit surfaces are coated with a high efficiency, narrowband, anti-reflection coating. We offer both broadband and single wavelength.

Standard Coating wavelength:
Narrow Band:-----488,532,632.8,650,808,850,980,1064,1310,1550nm
Broadband:------450-650,650-850,900-1200,1200-1550,1500-1610nm

The Working Principle of Aspheric Lenses(2024年02月02日)

ecoptik — 2024-02-02T15:26:55+0900

https://www.ecoptik.net/the-working-principle-of-aspheric-lenses.html

Aspheric lenses can improve image quality and correct imaging problems usually associated with spherical lenses. The original work and function of the aspheric lens are mainly reflected in the following aspects:

1. The spherical aberration of spherical lenses
In a spherical lens, light is focused at different distances (depending on where it enters relative to the edge of the lens), which can cause blur and peripheral distortion. This phenomenon is called spherical aberration.

Aspheric lenses advantages: aspherical lenses can reduce or eliminate this problem due to its unique design (with a shallower surface curvature angle). When light enters the aspheric lens, whether it enters or not, it will be focused to a point, resulting in a clearer and sharper image.

2. Distortion of spherical lens
When spherical lenses zoom in or zoom out an image, they will distort and bend the lines viewed through them. Since the edge power of the aspheric lens is low, the risk of pincushion distortion of the positive lens and barrel distortion of the negative lens can be reduced or eliminated.

3. Astigmatism at the edge of the spherical lens
Edge astigmatism refers to the unnecessary power gain that occurs in spherical and cylindrical mirrors when observing something from the optical center. It helps to create blurred images. Aspheric lenses avoid this situation by reducing the power gain along the edge of the lens.

Optical Products in Laser Optical System

Lasers have very good coherence, directivity and high concentration of energy.

The advent of the laser means that the optical element is no longer limited to the observation and recording of the original shape of the image, but the image is processed and recorded by the transformation of the time and space spectrum. In addition, in optical measurement, the use of laser precision is also higher than before.

Because the laser itself has very good coherence, when the material itself has defects, dust or bubbles, stripes, etc., it will be easy to produce noise, because the material is very strict in the selection, and in the processing process, the processing precision of the components to be very high requirements. Especially for the opposite type. Usually, it needs to be at least λ/10-λ /20 or so.

Brd optical focuses on high precision custom machining. we have a wealth of experience in laser products.

For example,

Planar optical elements, usually window pieces, laser beam splitters, etc. These elements are not only the measured datum plane but also the reference plane or wave plane segmentation element used as interferometer, which requires a high flatness.

With the development of laser technology, high power laser not only requires the element itself but also requires that it can withstand the corresponding damage threshold film layer

Plano-convex L lenses/Mirrors are positive focal length elements that have one spherical surface and one flat surface. These lenses are designed for infinite conjugate (parallel light) use or simple imaging in non-critical applications. The use of plano convex lens/mirror is ideal for all-purpose focusing elements.

If you want to know more information about a plano-convex lens/plano convex mirror, such as the use and refractive index of a plane convex lens, please contact us.

Description Of Plano Convex L Lens
Ecoptik Manufactures Plano Convex Lens.

The use of plano-convex cylindrical lenses: The plano-convex rectangular cylindrical lens can provide positive or negative focal length, which is very suitable for laser line generation or deformed beam shaping. It can be single-axis magnified in various optical applications to make the laser output circular. These plano-convex cylindrical lenses can be combined with other lenses to form a composite imaging system.

Plano Convex Lens Uses
The main application fields of plano-convex lens are far-infrared collimator, stage lighting, automotive lighting, outdoor road lighting, airport lighting and indoor special lighting, etc.

Plano Convex Lens VS Biconvex
First of all, from the imaging of the plano convex lens, the light incident on the two sides of the plano-convex lens has a slightly different refractive index. So, in fact, the focal lengths on both sides are also different. But when using, it cannot be reversed. There is also a type of "plano lens", which is different from plano-convex and biconvex lenses. The incident light is reflected and perpendicular to the parallel incident characteristics to continue straight forward, and no refracted light is produced; it is the middle. The flat glass optical element with the same thickness as the edge is called a flat lens, a biconvex lens, and the light incident on both sides has the same refractive index. The same goes for focal length. Plano-convex lenses have slightly different refractive indices for light incident on both sides. So actually the focal lengths on both sides are also different.

A convex lens is a lens with a thicker center and thinner edges. Convex lenses are divided into biconvex, plano-convex, and concave-convex (or positive meniscus) forms. A biconvex lens, the light incident on both sides has the same refractive index and the same focal length.

Plano-convex lens, one side is flat and the other side is convex. This type of lens is used to gather parallel light, or to convert point light sources into parallel light.

The main use of plano-convex lens are far-infrared collimator, stage lighting, automotive lighting, outdoor road lighting, airport lighting and indoor special lighting, etc.

Plano Cylindrical Convex Lens
A plano-convex cylindrical lens is used to condense light in one axis. A positive plano cylindrical lens is able to create a line image from a point of light, to change the aspect ratio of an image or to focus collimated input light to a line. Plano- convex cylindrical lenses are typically used for illumination of slit and line detector arrays, laser projection, laser line focussing and anamorphic beam shaping. If you have any demand, please contact Ecoptik (also known as BRD Optical).

Plano Convex Cylindrical Lens Descriptions
The Plano spherical lens acts symmetrically on the incident light in both directions, while the convex cylindrical lens acts in only one direction on the incident light. A typical application is to shape a deformed beam with a pair of plano-convex cylindrical lenses. A pair of positive plano-convex cylindrical lenses can be used to collimate and round the output of the laser diode. Another possible application is to focus the diverging beam onto the detector array with a single plano-convex cylindrical lens. In order to minimize the spherical aberration, when the collimated beams are concentrated into one line, the collimated light should be incident on the curved surface of the lens, and when the quasi-linear source is used, the line source should be incident on the plane of the lens.

Plano Concave Lens
Plano concave lens bend parallel input rays so they diverge from one another on the output side of the lens and hence have a negative focal length. The spherical aberration of the plano concave lenses is negative and can be used to balance aberrations created by other lenses. Similar to the planar concave lens, plane concave lens, the curvature surface usually faces the largest object distance or the infinite conjugate to minimize spherical aberration.

Penta Prism(2023年12月06日)

ecoptik — 2023-12-05T11:34:00+0900

https://www.ecoptik.net/products/penta-prism/

Half Penta Prism
Pentagonal prism is the beam Angle (90 °), one of the steering gear.It has two purposes: one is that no matter how much the first incident Angle on the side is the emergent light incident light steering Angle (90 °);The other is that, unlike a rectangular prism, the resulting image has neither rotation nor specular reflection. Pentaprism is commonly used in camera viewfinders, image observation systems or measuring instruments.

Description Of Penta Prism

Characteristics of pentagonal prism is a 90° Angle of the light became a vertical incidence, and then after the 45 ° Angle of two surface reflection, from the Angle of 90 ° exit, on the other side of the incident light and emergent light is equal to 90 ° Angle, such application pentagonal prism can turn axis around 90 °. Recently, the use of the characteristics of a pentagonal optical prism measurement [1] the planarity of the Pacific Ocean, namely the pentagonal prism rotates around the horizontal axis for emergent light in the vertical plane sweep out a plane, and vice around the vertical axis rotation, can be measured in horizontal plane, when using laser as light source, because the laser range far, you can sweep out a big plane, this for housing construction, large engineering construction of planar measurement obviously is simple and convenient and of high precision, so the pentagonal prism needs more and more.

Pentagonal prisms cannot achieve internal total reflection based on the critical-angle principle. Therefore, the two reflective surfaces of this prism are generally coated with aluminum film and black paint, and the incident and outgoing surfaces are coated with MgF2 single anti-reflective coating.

Optical Spherical Lens(2023年12月05日)

ecoptik — 2023-12-05T11:33:30+0900

https://www.ecoptik.net/products/optical-spherical-lens/

The "spherical curvature" of a spherical lens is constant, meaning that the front and back surfaces of the lens are part of the spherical surface, respectively. Each surface may be convex (protruding from the lens), concave (concave into the lens), or "flat" (flat). The line between the spherical centre points on the front and rear surfaces of the lens is called the optical axis of the lens. In almost all cases, the optical axis of the lens passes through the physical centre of the lens. Ecoptik (also known as BRD Optical) can provide different kinds of spherical lenses like plano concave lens, plano convex lens, achromatic lens.

The lens can be widely used in security, vehicle, digital camera, laser, optical instruments and other fields. With the continuous development of the market, lens technology is more and more widely used. Brd optical co. ltd has obtained the high technology of producing lenses. If any issues, please contact us.

The radius of curvature of the aspheric lens changes with the central axis, which has a better radius of curvature and can maintain good aberration correction. The aspheric lens is used to replace the spherical lens. The most significant advantage is that it can correct the spherical aberration caused by the spherical lens in the collimation and focusing system. By adjusting the surface constant and the aspheric coefficient, the aspheric lens can eliminate the spherical aberration to the greatest extent. The aspheric lens basically eliminates the spherical aberration caused by the spherical lens. At present, the main processes of the aspheric lens are: precision glass molding, precision polishing molding, hybrid molding,

What is the Difference Between Spherical and Aspheric Lenses?(2023年06月07日)

ecoptik — 2023-05-26T16:00:46+0900

https://www.ecoptik.net/what-is-the-difference-between-spherical-and-aspheric-lenses.html

What is a aspheric cylindrical lens? What is an aspheric lens? What is the difference between spherical and aspheric lenses? Why are aspheric lenses recommended? Let's talk about the difference between the two.

The spherical lenses have a spherical surface, and the radius of curvature of the entire lens is the same. On the contrary, the surface of an aspheric cylinder is more complicated, and the curvature gradually changes from the center to the edge. These design differences can reduce the number of elements in the assembly and result in thinner and lighter lenses.

The surface of the spherical lens looks like a part of a spherical or cylindrical surface.

The curve is the same across the entire surface. If you draw a straight line to follow the curve, it will form a circle. Because the design is simple, the spherical lens design is usually cheaper.

2. What is an aspheric lens?
Literally, it is easy to understand, this means that the lens is not spherical.

In addition, for a small number of people who are particularly sensitive to colors, such as wearing aspherical lenses will feel the rainbow phenomenon, you can try to replace the spherical lens.

Description Of Scanning mirror system
The scanning mirror of Ecoptik (also known as BRD Optical) is light weight rectangular mirror that used for high speed two-axis laser scanning system. The dimensions for each laser scanning mirror have been calculated accordingly with the laser beam size. The optical mirror has high reflectivity of 99.5% or above. The scanning mirrors are usually mounted on to a galvanometer for scanning purposes. For two axis scan mirror, commonly the Y mirror has a bigger size compared with the X mirror. This is due to the fact that the X mirror is used to scan the Y mirror rather than the object directly.

ecoptik — 2023-04-04T11:19:07+0900

https://www.ecoptik.net/products/plano-convex-cylindrical-lens/

A plano concave cylindrical lens is used to condense light in one axis. A positive plano cylindrical lens is able to create a line image from a point of light, to change the aspect ratio of an image or to focus collimated input light to a line. Plano- convex cylindrical lenses are typically used for illumination of slit and line detector arrays, laser projection, laser line focussing and anamorphic beam shaping. If you have any demand, please contact Ecoptik (also known as BRD Optical).

Plano Convex Cylindrical Lens Descriptions
The Plano spherical lens acts symmetrically on the incident light in both directions, while the convex cylindrical lens acts in only one direction on the incident light. A typical application is to shape a deformed beam with a pair of plano-convex cylindrical lenses. A pair of positive plano-convex cylindrical lenses can be used to collimate and round the output of the laser diode. Another possible application is to focus the diverging beam onto the detector array with a single plano convex cylindrical lens. In order to minimize the spherical aberration, when the collimated beams are concentrated into one line, the collimated light should be incident on the curved surface of the lens, and when the quasi-linear source is used, the line source should be incident on the plane of the lens.

Ecoptik (also known as BRD Optical) provides meniscus lens in both positive and negative focal lengths. These meniscus lenses are useful when used with another lenses to increase or decrease the focal length. This meniscus lens element configuration does not introduce any additional coma or spherical aberrations

Descripion Of Positive&Negative Meniscus Lens
Ecoptik (also known as BRD Optical) provides meniscus lenses in both positive and negative focal lengths. On the aspect of shape, it can be divided into convex meniscus lens and concave meniscus lens. On the aspect of the effect, it can be divided into diverging and converging meniscus lens.

Positive Meniscus Lens
A positive meniscus lens consists of two curved surfaces with similar radii of curvature and has a positive focal length. Positive meniscus lens are typically used for related applications such as reducing the focal length of another lens, increasing the numerical aperture, etc.In order to reduce spherical aberration, the beam should be incident on the convex surface of the lens when re-expanding or condensing or diverging collimated light is used; when it is used for converging light collimation, the beam should be incident on the concave surface.

Positive meniscus lenses are primarily used to minimize spherical aberration. When used in combination with another lens, a positive meniscus lens can reduce the focal length and increase the numerical aperture of the system without introducing significant spherical aberration. When used to converge parallel light, the convex surface of the lens should be oriented towards the direction of light emission in order to minimize spherical aberration. Coated lenses are also widely used in the visible and near-infrared fields.

Negative Meniscus Lens
A negative meniscus lens consists of two curved surfaces with similar radii of curvature and has a negative focal length.
Usually used to reduce the focal length of another lens, increase the numerical aperture and other related applications.
When used for focused beam collimation, the beam is incident on a concave surface. Negative meniscus lenses are mainly used to minimize spherical aberration.

Lightweight solution for mirrors(2023年)

ecoptik — 2023-02-23T15:10:29+0900

https://www.ecoptik.net/products/optical-mirror/

At present, there are two main ways to study the lightweight technology of mirror: casting forming method, high temperature welding or welding sealing method, and mechanical drill weight reduction method. Each of these three methods has its own advantages. The first two methods of processing the structure stiffness is relatively large, light weight, light weight rate can reach more than 70%, can ensure a higher surface accuracy of the mirror. Some oversized mirrors basically use the first two lightweight methods. For most mirrors of conventional caliber, the light weight of mirror structure is generally carried out by machining method. Mechanical drilling is an earlier method of mirror lightweight, which is achieved by mechanical drilling to remove the material on the mirror that does not participate in the imaging part of the optical system. At present, the commonly used methods include milling and drilling, ultra-Luo drilling, etc. The milling and drilling method controlled by computer can obtain the mirror with higher processing efficiency, higher lightweight degree and higher precision.

The shapes of the lightweight cells of the optical mirror mainly include triangular cells, quadrilateral cells, hexagonal cells, honeycomb cells, sector cells and circular cells, etc. The density and layout of the lightweight cells should be considered according to the requirements of the optical system on the surface shape of the primary mirror. Its form is shown in the figure.

The circular cells has good technological performance and is easy to process, but the lightweight rate is low. The fan-shaped lightweight cells is generally used for the lightweight of the circular mirror with a central cells. According to the different reinforcement arrangement is divided into continuous reinforcement type and intermittent reinforcement type of lightweight cells. In terms of machinability and structural rigidity, the structural rigidity of honeycomb cells is the best, and the technological performance of circular cells is the best. The technological properties of triangular cells, quadrilateral cells and fan-shaped cells are not much different. The structural stiffness of triangular cells and hexagonal cells is better, among which triangular cells are the best, but it is easy to form hot junction at the joint of triangular cells. Therefore, the thermal performance of triangular cells is not as good as that of hexagonal cells.

Ecoptik (also known as BRD Optical) can customize and process various high-precision optical components, such as spherical mirrors, aspheric mirrors, prisms, mirrors, filters, coating service, etc.

As one of optical mirror manufacturers, we will do our best to meet all the needs of customers.

Anamorphic Prism(2023年01月18日)

ecoptik — 2023-01-18T10:37:21+0900

https://www.ecoptik.net/products/anamorphic-prism/

An anamorphic prism pairs is a pair of prisms which is usually used for reshaping the profile of a laser beam. For example, the elliptical beam from a laser diode can be transformed into a beam with circular cross-section, as is needed for many applications, by using an optical prism pair as a beam expander for only one direction (e.g., the horizontal one). Of course, one can also just modify the ellipticity, or convert a circular beam into an elliptical one.

Anamorphic Prism Description

Diode lasers usually have elliptical beam profiles. In most cases, though, the shape of the circular beam is required, such as pattern matching with the external resonator to make the beam size adapt to the small aperture through the isolator. A deformed pair of anamorphic prisms is used to transform an elliptical laser diode beam into an approximately circular beam to amplify an elliptical beam in one dimension.

A dielectric mirror, also known as a Bragg mirror, is a type of mirror composed of multiple thin layers of dielectric material, typically deposited on a substrate of glass or some other optical material. By careful choice of the type and thickness of the dielectric layers, one can design an optical coating with specified reflectivity at different wavelengths of light. Dielectric mirrors are also used to produce ultra-high reflectivity mirrors: values of 99.999% or better over a narrow range of wavelengths can be produced using special techniques. Alternatively, they can be made to reflect a broad spectrum of light, such as the entire visible range or the spectrum of the Ti-sapphire laser. Mirrors of this type are very common in optics experiments, due to improved techniques that allow inexpensive manufacture of high-quality mirrors. Examples of their applications include laser cavity end mirrors, hot and cold mirrors, thin-film beamsplitters, and the coatings on modern mirrorshades.

Roof Prism(2022年)

ecoptik — 2022-11-15T17:16:49+0900

https://www.ecoptik.net/products/roof-prism/

The roof or Amici prism deviates or deflects the image through an angle of 90 degrees. It is a right-angle prism whose hypotenuse has been replaced by a 90-degree TIR roof. Glass that does not contribute to the clear aperture has been trimmed away to reduce size and weight.

Ecoptik Roof Prism is made from N-BK7, an RoHS compliant version of BK7, and can be used when a right angle deflection of an image or laser beam is required. In passing through the prism, the image is both deflected right-to-left and top-to-bottom. The hypotenuse of the optical prism utilizes total internal reflection (TIR) to reflect the image through the prism. Polarization states may become rotated during reflection.

The roof prism refers to the type of the prism construct used in the binoculars. In the roof prism design, the alignment of the binoculars is done in a straight line. This makes these binoculars a little sleeker and more compact than their porro prism counterparts. These binoculars can be easily identified as the objective lenses line up to the eyepieces in a near-linear fashion.

Roof prism binoculars are technically more complicated than prro prism binoculars. The reason for this is that the prisms used in roof prism binoculars must be produced with exceptional care and they must also be of a higher quality than prisms used in Porro binoculars. Roof prisms also require top-quality coating.The advantage of binoculars with a roof prism is that they have straight tubes where the front or objective lens is in line with the rear or ocular lens, whereas binoculars with a Porro prism have tubes that are offset or not in alignment with each other. Roof prism binoculars are therefore more compact and easier to take along with you. It is also easier to seal them, making their internal lenses watertight and less susceptible to dust and damage.Since the front objectives in roof prism binoculars are not out of alignment, as is the case with Porro binoculars, the perception of depth will be less than they would be with Porro binoculars.

The Ecoptik mirror with high reflectance can double the output power of the laser; it is reflected by the first reflecting surface, the reflected image is not distorted, and there is no ghosting, which is the reflection of the front surface. If a common optical mirror is used as the second reflecting surface, not only the reflectance is low, but also the wavelength is not selective, and ghosting is likely to occur. With the front coated film mirror, the obtained image is not only high in brightness, but also accurate and unbiased, the picture quality is clearer and the color is more realistic. Front surface mirror are widely used for optical high fidelity scanning reflection imaging.

Rod Lenses are polished on the circumference and ground on both ends. Optical performance is similar to a cylinder lens. Collimated light passing through the diameter of the rod lens will be focused into a line. Optical glass and UV Fused Silica substrates are available for a variety of UV, Visible, and NIR applications.

The optical rod lens is primarily used to change the design requirements for imaging size. For example, converting a spot into a line spot, or changing the height of the image without changing the image width. Rod lenses can be applied to linear detector illumination, barcode scanning, holographic illumination, optical information processing, computer, laser emission. Also, a cylindrical lens is used in high-power laser systems and synchrotron beamlines. At the same time, the requirements for rod lens parts are becoming higher and higher, especially in the high-power laser cavity and long-distance line interferometers. Such as high-precision test instruments and devices. As a professional optical manufacturer, Ecoptik (also known as BRD Optical) has these types of equipment. The cross-sectional refractive index is parabolically shaped and has a self-focusing effect on the beam, which can be used on an optical lens collimated by the fiber.

https://www.ecoptik.net/products/powell-prism/

The Powell lens is a quantum leap forward in line generator performance over the simple cylinder lens. A cylinder lens produces a poorly illuminated line, one limited by the non-uniform, Gaussian laser beam. The Powell lens' rounded roof is in fact a complex two-dimensional aspheric curve that generates a tremendous amount of spherical aberration that redistributes the light along the line; decreasing the light in the central area while increasing the light level at the line's ends. The result is a very uniformly illuminated line used in all manner of machine vision applications; from bio-medical and automobile assembly to chocolate chip cookie production.

Description Of Powell Prism
Powell prism (also known as laser linear generator lens) is an optical marking prism, which can be optimized for the input of laser beam with the diameter of 0.8mm. Powell optical prism makes the laser beam can be optimized into a straight line with uniform optical density, good stability and good linearity after passing through. Different from the cylindrical lens which produces the characteristics of central hot spot and faded edge gaussian beam, it can eliminate the distribution of central hot spot and faded edge of gaussian beam and form a straight line with uniform energy distribution. The full fan Angle ranges from 1° to 120°. The standard specifications are 5°, 10°, 20°, 30°, 40°, 45°, 50°, 60°, 70°, 80°, 90°, 110° and 120°.

Plano-convex L lenses/Mirrors are positive focal length elements that have one spherical surface and one flat surface. These lenses are designed for infinite conjugate (parallel light) use or simple imaging in non-critical applications. The use of a plano convex lens/mirror is ideal for all-purpose focusing elements.
If you want to know more information about a plano-convex lens/mirror, such as the use and refractive index of a plane convex lens, please contact us.

Description Of Plano Convex L Lens
Ecoptik Manufactures Plano Convex Lens.
The use of plano-convex cylindrical lenses: The plano-convex rectangular cylindrical lens can provide positive or negative focal length, which is very suitable for laser line generation or deformed beam shaping. It can be single-axis magnified in various optical applications to make the laser output circular. These plano-convex cylindrical lenses can be combined with other lenses to form a composite imaging system.
