Plano-Concex Cylindrical Optical Lens

Product description:

cylindrical glass lens

Cylindrical lens are used to corrent astigmatism in the eye and in rangefindere, to produce astigmatism, tretching a point of light into a line, they are widely used in bar code scanning, projection optics systems, laser measurement systems and holography.

Cylindrical lens are avaliable in either plano-concave configurations from Ruisen, plano-concave lens have a negative focal length and are used for image reduction or to spread light , plano-convex lens have a positive focal length, which make them idea for collecting and focusing light for many imaging applications.
