Product Detailes

A lens is an optical element made of a transparent material whose surface is a part of a spherical surface. The lens is composed of several lenses, including plastic and glass. Glass lenses are more expensive than plastic. Generally, the lens structures used for 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 a plastic lens. It plays an important role in astronomy, military, transportation, medicine, art and other fields.
