Arsenic Selenide

Used as a chalcogenide glass for infrared optics and fiber optics due to its high transparency in the mid-to-long wave infrared spectrum.

Fabricated into sputtering targets for the deposition of thin-film chalcogenide layers in phase-change memory and photonic devices.

Utilized as a source material in thermal evaporation processes to create amorphous thin films for infrared sensors and optical coatings.

Applied as a high-refractive index layer in multilayer optical coatings for infrared applications.
