GeAsSe is a chalcogenide glass ceramic composed of germanium, arsenic, and selenium—a material family valued for infrared transparency and nonlinear optical properties. This compound is primarily of research and specialized optics interest, used in infrared imaging windows, fiber optics, and thermal sensing applications where conventional optical materials become opaque. Engineers select GeAsSe-based compositions when extreme infrared wavelength transmission and chemical stability in harsh environments are critical, though production complexity and cost limit it to niche high-performance applications rather than commodity use.
