SOLUTION OF THE FILM SPECTRA EQUATION

Abstract

The work is analyzing the possibility of unambiguously determining the optical constants of films by spectrophotometric methods. The ambiguity of such a problem and the ways of its solution when using a spectrum section are shown. Based on the analysis performed, methods are considered for finding the optical constants of films with absorption. on the example of the film. The refractive indices of the CaY2F8 film have been determined in the range 1,3–17 μm.
