Paper Abstract

LaF 3 is presented as a possible high refraction index material for the interference coatings down to wavelength of 145 nm, if well-purified. A material shows up a negative inhomogeneity. The optical parameters of evaporated LaF3 layers are presented. The best mirrors based on LaF3-MgF2 system have a reflectivity up to 99% depending on absorption in layers.
