· JVASP-135645· GeTeAs

GeTeAs is a chalcogenide ceramic compound composed of germanium, tellurium, and arsenic elements, belonging to the family of amorphous or crystalline materials used primarily in infrared optics and photonic applications. This material is notable for its transparency in the infrared spectrum and is explored in research contexts for thermal imaging windows, infrared lenses, and specialized optical components where conventional glass is insufficient. GeTeAs represents an important class of materials for applications requiring broad infrared transmission and moderate environmental stability.

Regulatory Screening

Environmental

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
