Cylindrical lens is generally used to focus the incident light on the line or change the aspect ratio of the image. The double concave cylindrical lens has a concave cylindrical surface, so that the incident light can focus on a certain dimension and stretch the image, and the other side is concave. The focal length of double concave cylindrical mirror is negative, which is suitable for laser line generation or deformed beam shaping.
The Double Concave Cylindrical Lens is used in the industries like Optical display systems, imaging systems, optical instruments and laser systems.
