Saint-Gobain HS Grade Optical Fused Quartz
Categories: Ceramic; Glass; Oxide; Silicon Oxide

Material Notes: HS Grade Optical Fused Quartz is a high purity, low [OH] natural fused quartz. It has excellent IR transmission, useful transmission from 260 to 3500 nm, excellent visual quality with low bubbles, inclusions, and striae, and is available in a variety of sizes and forms. It is made by electric fusion of high purity quartz powder under vacuum conditions resulting in a low [OH] (ca. 5 ppm) material.

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.
