Ross Optical Industries 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.
