Produced naturally as a florite, it has appropriate refractive index variations for wavelengths and transmission to wavelengths from vacuum ultraviolet 125.0mm to infrared 12 .
It can be used as a prisim, lens, or window within a wide region from ultraviolet to infrared.
It is a chemically and physically stable crystal with excellent water resisitant, chemical resistant,and heat resistant characteristics.
Also, since it has unique optical dispersion(Abbe's number:95), it can be used as an achromatic lens(Apocromat) combined with other optical materials.
It can also be used as a laser crystal or radiation detection crystal by doping it with the appropriate rare earth elements.
Two kinds are manufactured:for visible, infrared use and for ultraviolet use(nonflourescent).
Recently, our company has succeeded in producing high quality Calcium Fluoraide single crystal for AvF Excimer Laser until good strain, homogeneity transmission and durability.
