Germanium Arsenic Selenide, Powder, 99.999%, -100 mesh approx

Germanium Arsenic Selenide is used as a sputtering target material to deposit chalcogenide thin films for infrared optics and phase-change memory applications.

As a chalcogenide glass, GeAsSe is utilized in the fabrication of infrared-transmitting optical components and waveguides due to its wide transparency range in the mid-to-long wave infrared spectrum.

Used as a source material for thin-film optical coatings to manage refractive index and transmission properties in specialized infrared sensor systems.
