General Introduction:
High purity gas smelting fused quartz glass, due to its SiO2 content in more than 99.99%, high purity, colorless transparent, bubbles and impurities, high UV light and visible light transmittance, and its thermal properties, chemical properties are excellent, is widely used as coating materials, used for mirror multilayer coating and anti-reflection coating.
Raytek is capable of producing, processing and supplying quartz glass materials for coating in various shapes and specifications such as granular, sheet, annular, spherical, cylindrical, etc
Main Characteristics:
A number of unique optical, mechanical and thermal properties have made quartz glass an indispensable material in the fabrication of high-tech products. they have the follwing main characters:
1).High chemical purity and resistance,
2).High softening temperature and thermal resistance,
3).Low thermal expansion with high resistance to thermal shocks,
4).High transparency from the ultraviolet to the infrared spectral range,
5).High radiation resistance.
6).The change of refractive index is very low;
7).High level of homogeneity;
8).The birefringence is very low;
9).Large size available;
10).Excellent transmittance from UV to IR;
11).Ultra low coefficient of thermal expansion;
12).Low cost
