Cylindrical lenses include plano-convex cylindrical lenses, plano-concave cylindrical lenses, biconvex cylindrical lenses, and biconcave cylindrical lenses. A cylindrical lens is a lens with different radii on the X axis and the Y axis, so the shape of the lens is cylindrical or semi-cylindrical, and only a single optical axis has image magnification. For example, converting a point spot into a line spot, or changing the image height without changing the image width, is an optical property unique to cylindrical lenses; with the rapid development of high technology, cylindrical lenses are being used more and more widely.
