Knight Optical (UK) Ltd Datasheets for Cylindrical Lenses

Cylindrical lens have at least one surface that is formed in the shape of a cylinder. Cylindrical lenses are used to correct astigmatism in the eye, and, in rangefinders, to produce astigmatism, stretching a point of light into a line.  This area includes micro cylindrical lenses as well.

Product Name Notes
As the name suggests cylindrical lenses have surfaces which are sections of a cylinder rather than the normal sphere normally used. Cylindrical lenses (cylinder lenses) are often used to change...
Calcium Fluoride (CaF₂) is commonly used for optics looking at the IR and UV spectrums and has a very low change in refractive index with wavelength. It shares similar optical...
Fresnel lenses consist of a flat surface with interspaced, concentric steps whereby each step corresponds to the surface of a conventional lens. Each step thereby acts as a refractive surface,...
Fused silica cylindrical lenses are widely used in the ultraviolet applications and these cylindrical lenses find many applications for beam handling in this spectral region. Like all cylindrical lenses they...
