Wholesale 1.56 Blue Block Hmc Optical Lens

Optical glass is the main raw material for lens production due to its high transparency, purity, colorless, uniform texture, and good refractive ability. Due to different chemical composition and refractive index, optical glasses include flint glass, crown glass, and lanthanum crown glass.

Mirrors are made according to the laws of refraction of light. A lens is a refractive mirror whose refractive surface is a transparent body with two spherical surfaces (part of a spherical surface) or one spherical surface (part of a spherical surface) and one planar surface. The images it forms include both real and virtual images. Lens can be widely used in various fields such as security, vehicle, digital cameras, lasers, optical instruments, etc. With the continuous development of the market, lens technology is also increasingly widely used.
