· JVASP-141183· LaAsS

LaAsS is a lanthanum arsenic sulfide ceramic compound belonging to the rare-earth chalcogenide family. This material is primarily of research interest for infrared optical and photonic applications, where its wide bandgap and potential for transparent window fabrication in the mid-to-far infrared spectrum make it relevant to the optical materials community. While not yet widely commercialized, LaAsS represents a class of exotic ceramics being investigated for specialized sensing, thermal imaging, and spectroscopic instrumentation where conventional optical materials reach their performance limits.

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.
