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-Concave Cylindrical lenses have a negative focal length and are used for image reduction or to spread light. Plano-Convex Cylindrical lenses have a positive focal length, which makes them ideal for collecting and focusing light for many imaging applications. Every sizes, materials cylindrical lenses are available according to your detailed parameters.
We supply kinds of plano-convex cylindrical lens, plano-concave cylindrical lens, bi-convex cylindrical lens, bi-concave cylindrical lens, meniscus cylindrical lens, Rod cylindrical lenses, special cylindrical lens etc..
