Optical lens

A thin lens is a lens in which the thickness of the central portion is large compared with the radius of curvature of both sides thereof. In the early days, the camera was equipped with only one convex lens, so it was called a "single lens". With the increasing development of science and technology, modern lenses have a number of different forms and functions of convex and concave lenses to form a converging lens, called "compound lens". The concave lens in the compound lens serves to correct various aberrations.
