About Calcium Fluoride (CaF2)
Calcium Fluoride (CaF2) is a low-dispersion optical crystal with exceptional transmission from deep ultraviolet (UV) through mid-infrared (MIR). With transmission from 0.13 to 9 μm and very low refractive index, CaF2 is ideal for broadband optical systems, laser optics, and applications requiring minimal chromatic aberration.
