Fused Silica - RP Photonics

Fused silica is sometimes called fused quartz or quartz glass. However, it should be kept in mind that it is an amorphous material, while quartz is crystalline. (When lamps are said to have a quartz envelope, it is always fused silica; the same holds for most “quartz tubes”.) Other common names are silica glass and vitreous silica.
