Calcium Flouride (CaF₂)

Calcium Fluoride as an optical substrate refers to a crystalline material manufactured into precision windows, lenses, prisms, and optical components. Known for its broad transmission range from the ultraviolet (UV) through the infrared (IR) spectrum, low refractive index, and low chromatic dispersion, calcium fluoride is commonly used in UV imaging, spectroscopy, laser systems, and infrared instrumentation.
