optical bi-concave cylindrical irregular lens AR coating

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, Plano-Convex Cylindrical Lens or 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. 

Plano-concave Cylinder Lens commonly used to turn a collimated laser source into a line generator. These Plano-concave Cylinder Lens and Illumination Grade plano-convex Cylindrical lens can be used together for beam expander applications.

Other types of Cylindrical lens such as Double-Convex Cylinder Lens,Double-concave Cylinder Lens, meniscus cylinder lens or Rod Cylinder Lens are available according to your detailed parameters.
