The lens is an optical element made of a transparent material whose surface is part of a spherical surface. The lens is composed of several lenses, including plastic lenses and glass lenses. Glass lenses are more expensive than plastic. Usually the lens structures used in cameras are: 1P, 2P, 1G1P, 1G2P, 2G2P, 4G, etc. The more lenses, the higher the cost. Therefore, a high-quality camera should use a glass lens, and its imaging effect is better than that of a plastic lens, and it plays an important role in astronomy, military, transportation, medicine, art and other fields.

Lenses can be widely used in various fields such as security, automotive, digital cameras, lasers, optical instruments, etc. With the continuous development of the market, lens technology is becoming more and more widely used. (lens) lenses are made according to the laws of refraction of light. A lens is an optical element made of transparent substances (such as glass, crystal, etc.). The lens is a refractor whose refraction surface is a transparent body with two spherical surfaces (part of the spherical surface), or a spherical surface (part of the spherical surface) and a plane. It has both real and virtual images.

Convex lens: thick in the middle, thin in the edge, there are three kinds of biconvex, planoconvex, and concave;

Concave lens: thin in the middle and thick at the edge, there are three types: double concave, plano-concave, and convex-concave.
