Detail

Parameters

Highly pure fused quartz glass, it contains more than 99.99% SiO2, colorless, transparent, bubble-free, high transmission at UV and Visible spectrum. With excellent thermal performance and chemical performance, our quartz glass is widely used as a coating material to do the coating of the mirror surface and antireflection coating.

We can produce and process various shapes and sizes of quartz glass such as granular, sheet, ring, ball, and columnar. Also we supply instruments and parts made in quartz glass for vacuum coating machine.
