Abstract

To obtain wide-band antireflection coatings for the visible and the middle IR regions of the spectrum transparent optical films with different refractive indexes and small absorption coefficients are required. Promising BaF₂, CaF₂, SrF₂ films with optical thickness more than 3 - 5 micrometers are not transparent in the visible region. Alloyed BaF₂ films, which were transparent in the all mentioned diapason, were obtained and investigated. Spectra selective coatings which based on alloyed BaF₂ were synthesized, made and researched for the visible and the middle IR range. The synthesis was realized on the base of the method of equivalent layers.
