Saint-Gobain Vitreosil® 055 Optical Fused Quartz

 

Subcategory: Glass; Oxide, Silicon; Oxide

Material Notes:
Vitreosil® 055 is the highest grade of optical grade fused quartz available from Saint-Gobain Quartz for use in the near UV and visible. It has a useful transmission range from 270 nm in the near UV to 2000 nm in the IR.

Vitreosil® optical fused quartz is made by flame fusion of naturally occurring quartz crystal in an oxy-hydrogen flame. Darkens slightly after prolonged UV exposure. Darkens after 107 RAD X-ray or gamma ray exposure.

General properties of Fused Silica and Fused quartz: A very wide transmission range from UV to near IR; extremely high optical transmission, excellent resistance to high power laser energy, excellent homogeneity, high temperature resistance, very low thermal expansion (resistance to thermal shock), and chemical inertness. General uses for optical quartz are microlithography optical systems, optical fibers, photomasks, laser optics, LCD displays, light guides, optical, IR , and UV windows, spectrophotometer cells, slides, optical pyrometers, and lamp bodies/components.
