Abstract

The influence of thickness (d_t) and refractive index of the transition film-substrate region at different regularities of the change in n_t from the interface n_t equals 2.6 to the central part of the film n_f equals 2.05 on spectral characteristics of quarter-wavelength films with an operating length (lambda) ₀ equals 400 nm has been considered. The regularities of the change in the extremum (T_min) and frequency position of (lambda) _o depending on the thickness d_t varying from 0 to 300 nm with the increment of 30 nm have been modeled. A stepwise character of the distribution n_t has been found to have the largest influence on the change in T_min and (lambda) ₀. The results of the influence of thickness and character of the change in n_t in a high-refractive layer of 11-layer rejection filter S - BH...HB on the position of T_min and (lambda) _o are given.
