Essential components in optical glass vision systems

Date:2017年12月14日 00:10

Optical glass can modify the direction of light transmission and can modify the relative spectral dispersion of ultraviolet, visible or infrared light. Optical glass has stable optical properties and high optical uniformity. Optical glass has the advantages of high temperature resistance, low expansion coefficient, high mechanical strength and good chemical properties. It is used to produce prisms and lenses with special requirements for various wavelengths. Windows and mirrors, etc.

Optical glass lens is an indispensable component of machine vision system, which directly affects the quality of imaging quality and affects the implementation and effect of the algorithm. Since different glass types have different characteristics, it is very important to choose an optical glass material.

About the advantages and performance of optical glass

1. The transmittance of optical glass is high ---- the light transmittance can reach 92%. If the surface of the lens is coated with one or more layers of magnesium fluoride antireflection film, the transmittance of the lens can reach 99.2%.

2, optical glass chemical stability ---- acid, alkali and other chemical corrosion.

3. The refractive index of the optical glass is constant and accurate ---- the refractive index is 1.523, constant and accurate, and the diopter after processing is accurate.

4, optical glass absorbs ultraviolet light - to avoid damage to the eyes caused by ultraviolet rays.
