Calcium fluoride (CaF2) optical window GCL-1203 series

Daheng Optics' offers calcium fluoride (CaF2) uncoated windows. The uncoated windows provide high transmission from the ultraviolet (200 nm) to the infrared (8 μm).Calcium fluoride has a low absorption coefficient and high damage threshold, making these windows a good choice for use with free-space lasers. Optical calcium fluoride offers low dispersion (with an Abbe Number of 95) and low fluorescence, as well as excellent water, chemical, and heat resistance. In dry environments, CaF2 can be used up to 1000 °C, but in the presence of moisture, degradation will occur for temperatures exceeding 600 °C. CaF2 windows are also commonly used in cryogenically cooled thermal imaging systems. Daheng Optics' offers calcium fluoride (CaF2) uncoated windows.
