50 x 25 mm N-BK7 PCV cylindric lenses

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 cylindric lens or plano-convex cylindrical configurations. Plano-Concave Cylindric lens (PCV cylinder lens) has a negative focal length and are used for image reduction or to spread light. Plano-Convex Cylinder lens (PCX Cylinder lens) has a positive focal length, which makes them ideal for collecting and focusing light for many imaging applications.  Every sizes,materials optical glass cylindrical lens are available according to your detailed parameters.

We supply kinds of plano-convex cylindrical lens(PCX cylindrical lens),plano-concave cylindrical lens,bi-convex cylindrical lens,bi-concave cylindrical lens,meniscus cylindrical lens,Rod cylinder lens,special cylindrical lens etc..
