Detailed introduction
Cylindrical lens is different from spherical lens. Spheical lens acts symmetrically on the incident light in both directions, while cylindrical lens acts on the incident light in only one direction. Cylindrical lenses are generally used to focus parallel or divergent beams onto the line or to change the aspect ratio of the image. Cylindrical lenses are generally designed for applications that require one-dimensional shaping of the light source. There are two structures, plano-concave and plano-convex, which are used for diverging or converging beams respectively.
