100 mm Corning 7980 High Purity Fused Silica (HPFS) Wafer, 500 um Thick, DSP, w/ Bevel, Primary Flat Only

Corning High Purity Fused Silica (HPFS) 7980 is a high purity non-crystalline silica glass with excellent optical qualities. It has extraordinarily low refractive index variations, low
birefringence values, ultra-low thermal expansion coefficient and exceptional transmittance from the deep ultraviolet through the infrared region. This wafer is made by HPFS 7980 wafer grade material which has a ultra-high purity, no inclusions detected under high-intensity illumination and 800~1000 ppm content OH.

  • Exceptional transmittance across a broad range

Fused silica (SiO2) wafers are made from high purity fused silica, ground and polished to optical grade on both sides. The fused silica wafers are suitable for many optical applications because of their excellent optical transmission characteristics. Fused silica also has excellent chemical resistance against a wide variety of solvents, as well as exceptional heat resistance, with high dimensional stability over a wide temperature range thanks to its ultra low thermal expansion coefficient.

Single Crystal Quartz Wafers and Substrates are also available.
