From the laboratory, calcium fluoride is commonly employed to be a window product for both of those infrared and ultraviolet wavelengths, because it is clear in these areas (about 0.fifteen µm to 9 µm) and exhibits a very low change in refractive index with wavelength. Also, the material is attacked by couple of reagents. At wavelengths as shorter as 157 nm, a standard wavelength utilized for semiconductor stepper manufacture for built-in circuit lithography, the refractive index of calcium fluoride exhibits some non-linearity at significant energy densities, which has inhibited its use for this objective.
