Abstract

Layered-inhomogeneous model of the refractive index profile, which includes primary and transition region is developed, the effect of the transition region with inhomogeneous distribution of the refractive index on the spectral characteristics of narrow-band filters depending on the angle and polarization is investigated in the paper. The basic dependencies of the change in parameters of transmission spectra of multilayer interference structures of narrow-band optical filters depending on the polarization and incidence angle in the presence of the transition region are given. The results obtained are important for determining the efficiency of using convergence or divergence of radiation fluxes in optical systems. The features of spectral characteristics of partially inhomogeneous films with different types of distribution of the refractive index at interfaces are defined. These features of spectral characteristics allow to extend the possibility to use films of non-crystalline materials in designing and manufacturing of narrow-band optical filters.
