Cylindrial Lens Cylinder Lenses are offered in both plano-concave and plano-convex configurations, they are typically used to focus incoming light to a line, or to change the aspect ratio of an image. Cylinder Lenses are available with positive or negative focal lengths, they are used for the optics, lasers, medical science, electronics, tele-communication and others. Worldhawk can offer cylinder Lenses include convex cylindrical lens, concave cylindrical lens, meniscus cylindrical lens, and doublet achromatic cylindrical lens ect. Choose from N-BK7 glass, UV fused silica, or CaF2, all of which are available uncoated or with an antireflection coating. Worldhawk can provide various kinds of cylindrical lens with high precision, We are proud to be one of the few suppliers can detection the radius and flatness about the cylindrical lens in China. Absolutly can ensure all the products are qualified.
