Plano-concave cylindrical lens is an optical component in which one surface is plano and the other has a cylindrical shape curved inward. Plano-concave cylindrical lens  act as plano-concave spherical lens, but it spreads and diverges light only in a single dimension. In order to reduce spherical aberrations collimated light should incident onto the curved surface of the lens. Clindrical lens can be used as a mirror substrate when a concave reflective surface is required. Also, a pair of plano-convex and plano-concave cylindrical lenses are used in anamorphic beam shaping applications. 4Lasers offer various focal length plano-convex cylindrical lenses made from borosilicate crown glass BK7 and UV grade fused silica. In order to achieve optimized transmission ratio anti-reflection coatings are generally applied on to the cylindrical lens input and exit surfaces.
