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 Cylinder Lens or plano-convex cylinderical lens configurations. Plano-Concave Cylindrical lens has a negative focal length and are used for image reduction or to spread light. Plano-Convex Cylinder lens has a positive focal length, which makes the cylindrical lens ideal for collecting and focusing light for many imaging applications. Every sizes,materials cylindrical lens are available according to your detailed parameters.
Some styles of cylindrical lens have antireflective coatings to increase the transmission of light through the cylindrical lens.
Fused silica cylindrical lens is ideal for demanding laser machining and medical applications.
