Positive achromatic cylindrical lenses are made of two cylindrical lenses with different refractive indices and different dispersion rates. They can reduce chromatic aberration and spherical aberration to a greater extent, and can better control Incident light is focused into a line, and the double-glued design further optimizes lens performance.

Therefore, achromatic lenses have significant advantages over monolithic lenses of equal diameter and focal length. It is more suitable for broadband light sources, reduces chromatic aberration to a greater extent, and can produce concentrated lines or clear irregular-shaped images with less dispersion. It is widely used in laser shaping, laser projection and other related fields.

AOS Optics provides a variety of cylindrical lenses, including plano-convex cylindrical lenses, plano-concave cylindrical lenses, positive cemented achromatic cylindrical lenses, etc. It can provide double-sided anti-reflection coating for cylindrical lens products, which can greatly reduce the reflection on the surface of the element and increase its transmittance. The anti-reflection coating includes UV, VIS, NIR, SWIR, IR1 and IR2. A variety of materials are available, H-K9L optical glass substrates are suitable for visible light and near-infrared band applications, germanium, silicon, zinc selenide, and calcium fluoride substrates are suitable for infrared applications, and fused silica is suitable for ultraviolet applications.
