| Message: | Calcium Fluoride (CaF2) crystal have good performance at 0.13~10 μm wavelength range, wide range of light.CaF2 cyrstal is transparent over a broad range from ultraviolet (UV) to infrared (IR) frequencies.
Calcium Fluoride (CaF2) is used to manufacture optical components such as windows and lenses, used in thermal imaging systems, spectroscopy, and excimer lasers, Fourier analysis, testing instruments, gas liquid laser system, astronomical telescope, MIR/NIR imaging system, etc.
