Optical Properties of Fused Quartz

The optical properties of fused quartz allows you to choose between various types, because the degree of transparency defines material purity and the method of manufacture.

Certain indicators are the UV cutoff and the presence or absence of bands at 245nm and 2.73µm. The UV cutoff varies from 155 to 175nm for a 10mm thick test sample. The presence of transition metallic impurities will move the UV cutoff towards longer wavelengths.
