Saint-Gobain Vitreosil® CFQ/TSC Optical Fused Quartz
Categories:	Ceramic; Glass; Oxide; Silicon Oxide
Material Notes:	Vitreosil® CFQ/TSC grades are for use in less demanding applications including viewing windows for use in corrosive and high temperature environments and non-optical components such as spacers, insulators, etc. 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.
