Optics - Lenses

The KNAC2408B is a monochromatic aspherical lens that is designed to deliver superior optics performance in a wide range of applications. This lens is manufactured from optical grade crown glass and features a high index of refraction. It is especially well-suited for use in wide-angle lenses, zoom lenses, and telephoto lenses.

Applications

Due to its superior optical characteristics, the KNAC2408B is ideal for use in a number of different optics applications. It can be used for a variety of imaging applications, such as digital photography, video recording, microscopy, and infrared imaging. It is especially suitable for use with CCD and CMOS imaging sensors due to its wide field of view and high resolution. Furthermore, its high refractive index makes it well-suited for use in high-resolution optical systems, where it can provide better image quality and clearer details.

In addition, the KNAC2408B is suitable for use in beam projection and laser beam focusing applications. It is capable of providing a high intensity beam with a good degree of accuracy and precision. This makes it ideal for use in medical, industrial, and optical research settings, where precision and accuracy is of utmost importance. Additionally, this lens can also be used for dark field imaging and the detection of downconverted laser beams.

Design and Construction

The KNAC2408B is a monochromatic aspherical lens constructed of optical grade crown glass. This gives it excellent optical characteristics such as high transmittance, excellent light transmission, and low chromatic aberration. It has an index of refraction of 1.88 and a wavelength range of 350–700nm.

The lens consists of two basic parts: the optical element and the housing. The optical element is composed of eight aspherical lenses which are arranged in alternating spherical and cylindrical planes. It also includes two focusing lenses and a biconvex lens to provide optimal image quality. The housing is made from anodized aluminum and is designed to be lightweight and corrosion resistant.

Working Principle

The working principle of the KNAC2408B aspherical lens is based on its ability to refract light. When light passes through the lens, it is bent in a curved path. This curved path allows the lens to provide a wider field of view and a higher resolution image. The light is then focused on the imaging sensor or other device to produce the desired image.

Light bends differently due to the difference in refractive index of different materials. This is why the KNAC2408B features a high index of refraction. The higher the index of refraction, the more the light will be bent and the higher the resolution of the image will be. The lens also features a high level of absorptivity, which allows it to absorb a certain percentage of the light passing through it in order to reduce glare and ghost images.

Conclusion

The KNAC2408B is a monochromatic aspherical lens designed to provide superior optical performance in a wide range of applications. It is composed of optical grade crown glass and has a high index of refraction, making it ideal for use in high-resolution optical systems for imaging, beam projection, and laser beam focusing applications. Its working principle is based on refraction of light, which is bent due to the difference in refractive index between materials.
