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.

| 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... |
