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.
