CaF2
Nikon Calcium Fluoride (NICF) Series comprises a single-crystal optical material that features homogeneity in refractive index and high transmittance, for greater durability when used with various types of lasers, from excimer lasers to vacuum ultraviolet lasers.
Nikon Calcium Fluoride was originally developed to accommodate the excimer laser light sources installed in microlithography unites of extreme precision and durability.
In working with CaF2 to match our customer requirements, Nikon is capable of factoring in any material-grade specification or mass-production criterion using proprietary accurate analysis technology and material measurement
