UV Fused Silica is the standard bearer for UV/VIS applications. Compared to Optical Glass, Fused Silica can be used at higher temperatures (up to 1050ºC) and at wavelengths deeper into the UV range (180nm). 

With excellent chemical resistance, resistance to thermal shock, hardness and durability, this is a common choice for aerospace, scientific instrumentation and industrial applications. 

Firebird provides these in several uncoated stock configurations but can provide customized and coated to your specifications.
