Investigation of the influence of errors the parameters of the layers of optical filters on the stability of their spectral characteristics

Abstract

Mathematical modeling is performed in order to analyze the effects of technological errors originated from partial inhomogeneity, variations of the refractive index and the differences in geometric thickness of layers with high refractive index on spectral characteristics of narrow- and wide-band filters. Using a Monte Carlo method the influence of technological errors on optical parameters of the layers and their influences on spectral characteristics of interference filters are investigated and discusses in details.
