Germanium selenium Antimony Arsenic Tellurium- Chalcogenide-Glass, Powder, 99.99%, -325 mesh

Used as a high-purity sputtering target material for the deposition of complex chalcogenide thin films in phase-change memory and infrared optical applications.

Utilized as a multi-component chalcogenide glass for infrared-transmitting lenses and sensors due to its broad transparency range in the mid-to-long wave infrared spectrum.

Applied as a thin-film coating material to modify the refractive index and infrared transmission properties of optical components.
