· Ca1 F2

Calcium fluoride (CaF₂) is an ionic ceramic compound belonging to the fluorite crystal structure family, valued for its exceptional optical transparency across a wide spectral range from the ultraviolet through the infrared. It is widely used in optical and thermal applications where conventional glasses are unsuitable, including precision optics, thermal imaging systems, and high-energy laser components, owing to its low refractive index, minimal dispersion, and excellent thermal stability. Engineers select CaF₂ over silicate glasses when applications demand deep UV transmission, high-temperature stability, or operation in the infrared spectrum, though its brittleness and hygroscopic surface require careful handling and environmental control.

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.
