Arsenic Sulfide

Arsenic sulfide is a chalcogenide glass used in the fabrication of infrared-transmitting optical fibers, waveguides, and photonic devices due to its high transparency in the IR spectrum.

Used as a sputtering target material for the deposition of thin-film chalcogenide layers in phase-change memory and specialized optical coatings.

Applied as a thin film via vacuum deposition to create high-refractive index layers for infrared optical components and filters.

Utilized as a source material in thermal evaporation processes to produce amorphous thin films for infrared sensing and imaging applications.
