Cylindrical Lens

Cylindrical lenses

Cylindrical lenses are generally used to focus parallel or divergent beams onto a line or to change the aspect ratio of the image. Cylindrical lenses are generally designed for applications where one-dimensional shaping of the light source is required. They have two structures, flat - concave and convex, which are used for divergent or converging beams respectively. Plano-convex cylindrical lenses focus the incoming light onto the line and have a positive focal length consisting of one plane and one convex cylinder, while plano-concave cylindrical lenses have a negative focal length consisting of one plane and one concave cylinder.
