Description
Cylindrical lens are generally used to converge parallel or diverging beams to a line or to change the aspect ratio of an image. Cylindrical lens can be divided into two structures: plano-convex and plano-concave, both of which are used to converge or diverge beams, respectively. A wide range of materials and coatings of Cylindrical lens are available for UM OPTICS, such as CaF2, K9, UVFS, Si, Ge and ZnSE, to meet different customer needs.
