· MgF2

Magnesium fluoride (MgF₂) is an inorganic ceramic compound valued for its exceptional optical transparency across a broad spectrum, including ultraviolet through infrared wavelengths. It is widely used in precision optics and photonic applications where standard glass materials would absorb or scatter light, and is chosen over alternatives due to its superior transmission in the deep UV region and excellent chemical stability in harsh environments.

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.
