Optical ge convex cylindrical lens

Product Description

Cylindrical lens is used to correct astigmatism in the eye, and, in rangefinders, to produce astigmatism, stretching a point of light into a line.They are available in either plano concave or plano convex configurations.Plano-Convex Cylindrical lenses have a positive focal length, which makes them ideal for collecting and focusing light for many imaging applications. We supply kinds of plano-convex cylindrical lens,plano-concave cylindrical lens,bi-convex cylindrical lens,bi-concave cylindrical lens,meniscus cylindrical lens,long cylindrical lens,special cylindrical lens etc..
