Fused Silica (SiO2) UV Grade

Fused Silica comes in IR and UV grades. The UV grades are sold under several trade names including Suprasil. This material is sometimes referred to by the misnomer crystal quartz. Synthetic crystal quartz is bi-refringent and its applications differ from those of fused silica. The UV grade of this material is useful for UV applications, which include spectroscopy cuvettes and applications at 1064nm such as YAG laser protective windows.
