Optical Lens
Lenses are used in optical systems for beam convergence, beam expansion, imaging and collimation. According to the structure of the lens, they can be roughly divided into single lens (plane convex, plane concave, double convex, double concave and other different shapes) and cemented lenses, combination lens group and other different types.
