Fused Silica (SiO2) Windows
and Rods
Fused silica is the amorphous form of
quartz. Advantages of fused silica
material include the extremely good transparency from UV to IR, low
coefficient of thermal expansion, large resistance to thermal shock over
large temperature excursions, wide thermal operating range and high
laser damage threshold. Various high quality HR, AR, and partial
reflective coatings are available on fused silica faces.
