Optical Material
Origin
China

Calcium fluoride (CaF2) is a single-crystal material highly esteemed for its excellent optical properties, known in precision optics for its broadband transparency and low dispersion. Its crystal structure gives it high transmittance from the ultraviolet to the mid-infrared, along with low thermal expansion and strong chemical stability, ensuring consistent performance in extreme temperature or corrosive environments. CaF2 has laser damage resistance and low optical loss, and is widely used in UV lithography optical elements, infrared spectrometer prisms, and laser system windows/lenses, especially in applications requiring low dispersion and broadband transmission.
