Optical glass lens is an indispensable component in the machine vision system, which directly affects the quality of the imaging quality and affects the implementation and effect of the algorithm. Because different glass types have different characteristics, it is important to choose an optical glass material.
Optical glass can change the direction of light transmission, and can change the relative spectral dispersion of ultraviolet, visible or infrared light. Optical glass has stable optical properties and high optical uniformity. It has the advantages of high temperature resistance, low expansion coefficient, high mechanical strength, and good chemical properties. It is used to make prisms, lenses, windows and Reflectors and so on.
1. Optical glass is chemically stable-resistant to corrosion by acids, alkalis and other chemical substances.
2. The refractive index of optical glass is constant and accurate-the refractive index is 1.523, which is constant and accurate, and the refractive power is accurate after processing.
3. Optical glass absorbs ultraviolet rays-to avoid damage to the eyes by ultraviolet rays.
4. Optical glass has high light transmittance-the light transmittance can reach 92%. If the lens surface is coated with one or more layers of magnesium fluoride antireflection film, the light transmittance of the lens can reach 99.2%. ccd optical glass, wire laminated glass
