As₂S₃ is an inorganic ceramic compound belonging to the chalcogenide glass family, combining arsenic and sulfur in a stable stoichiometric form. This material is primarily used in infrared (IR) optics and photonics applications, where its transparency in the mid- to long-wave infrared spectrum makes it valuable for thermal imaging systems, spectroscopy, and sensing devices. As₂S₃ glass is also investigated for photonic applications including all-optical switching and fiber optics, offering advantages over silica-based systems in specific wavelength ranges, though handling and disposal require careful attention due to arsenic content.
