MSE PRO 6 inch Corning 7980 High Purity Fused SIlica (HPFS) Wafer, 1100 um thick, DSP
Introduction
Corning 7980 is a high-purity synthetic amorphous silicon dioxide manufactured via flame deposition. This noncrystalline, transparent silica glass stands out for its impressive optical and thermal properties, making it an excellent choice for applications in the photonics and semiconductor industries. With high transparency across a wide wavelength range, HPFS Corning 7980 performs especially well in UV and visible light, achieving transmission rates typically above 90% from 200 nm to 2,500 nm.
Its low thermal expansion, strong resistance to thermal shock, and high durability against chemical and environmental degradation make it suitable for precision applications.
