· BaF2

Barium fluoride (BaF₂) is an ionic ceramic compound valued for its optical transparency across a broad spectrum, from the ultraviolet through infrared regions. It is widely deployed in optical systems, laser windows, and spectroscopic instruments where conventional glass would absorb or scatter radiation. Engineers select BaF₂ over alternatives like CaF₂ or fused silica when demanding applications require excellent transmission in both near-UV and mid-infrared bands, combined with reasonable mechanical stiffness and resistance to thermal shock.

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.
