Material Information
Fused Silica & Quartz
The optical properties of quartz are unique. It can penetrate both the far ultraviolet spectrum and all the ultraviolet materials better, as well as the visible and near infrared spectrum. Customers can choose from the range of 185-3500m band according to their needs. Quartz glass is an essential optical material for high stability optical system in various bad situations because of its high temperature resistance, small thermal expansion coefficient, good chemical thermal stability, bubble, stripe, uniformity and birefringence.
