· JVASP-131919· Ge7Se

Ge₇Se is a germanium-selenium chalcogenide ceramic compound belonging to the family of amorphous or crystalline semiconducting materials. This material is primarily of research interest for infrared optics and photonic applications, where its transparency in the mid- to far-infrared spectrum makes it valuable for optical windows, lenses, and sensor components that operate beyond the visible range. Ge₇Se is notable for its potential in thermal imaging systems and infrared spectroscopy instrumentation, offering advantages over conventional optical materials in applications requiring transmission in extended infrared wavelengths, though it remains less common in high-volume commercial production compared to established alternatives like germanium or zinc selenide.

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.
