Optical coating material

Common optical coating materials are as follows:

1. Magnesium fluoride

Material features: colorless tetragonal powder with high purity. Using it to prepare optical coating can improve transmittance without collapse point.

2. Silica

Material features: colorless transparent crystal, high melting point, high hardness and good chemical stability. It has high purity and can be used to prepare high-quality SiO2 coating with good evaporation state and no collapse point. According to the use requirements, it is divided into ultraviolet, infrared and visible light.

3. Zirconia

The material features white heavy crystalline state, high refractive index and high temperature resistance, stable chemical properties and high purity. It can be used to prepare high-quality zirconia coating without collapse point.
