• Corning 7980 is a high‑purity synthetic amorphous silica produced via flame hydrolysis deposition. This transparent non‑crystalline silica glass stands out for its remarkable optical and thermal properties, making it an excellent choice for applications in the photonics and semiconductor industries. Featuring high transmittance across a broad wavelength range, Corning 7980 HPFS performs exceptionally well in the ultraviolet and visible spectra, with typical transmission exceeding 90% from 200 nm to 2500 nm. Its low thermal expansion, strong thermal shock resistance, and high durability against chemical and environmental degradation suit it for precision applications.
• Corning 7980 is available in various grades for different applications, such as Grade 7980 ArF and Grade 7980 KrF. While JGS1 and JGS2 substrates are widely used in standard optical applications, Corning 7980 delivers enhanced optical performance and thermal stability. These attributes make Corning 7980 particularly suitable for high‑precision optics and demanding photonics applications.
• Corning 7980 substrates are available in sizes ranging from 4 inches to 8 inches, and are commonly used in applications including optical windows, laser components, photolithography, and precision optical fabrication.
