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 chang...
For example, when it is a thin lens, the distance between the two focal points and the center of the lens is approximately equal. The focal length of a convex lens is the distance from the focal point to the center of the lens. The smaller the spherical radius of the co...
