Polished square quartz plate

Quartz glass has an extraordinary high optical transmissivity for ultraviolet light.

Due to its low coefficient of thermal expansion, quartz glass can withstand very high operating temperatures.

The very good UV-light transparency(over 92%) of quartz glass can not be outperformed by any other industrial glass material.

This raw quartz glass material is sawn, ground, polished and shaped according to customer's specifications.

Mainly applies to special light source, optical instrument, photoelectron, military industry, metallurgy, semiconductor, optical communication, etc
