Calcium Fluoride (CaF2) rectangular PCV cylinder lens

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 Cylindrical Lens and Meniscus Cylinder Lens configurations. Plano-Concave Cylinder Lens has a negative focal length and are used for image reduction or to spread light. Plano-Convex Cylindrical 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.

Other types of plano-convex cylindrical lens,plano-concave cylinder lens,double-convex cylindrical lens,Double-Concave Cylindrical Lens,Meniscus Cylindrical Lens,Rod cylindrical lenses,special cylindrical lens could be customized upon request.
