Nonpolarizing Interference Systems Containing Metallic Layers

Abstract

The structure of nonpolarizing interference systems incorporating the layers manufactured from metallic materials is considered. The method of searching for the structures of metal-dielectric interference systems providing a small deviation between the spectral characteristics of the energy reflection (transmission) coefficient for s- and р-polarizations is presented. The structures developed on the basis of the presented method have a rather simple structure, which makes them easy to implement. The analysis of the spectral characteristics of the obtained structures has demonstrated that the difference between the integral refl-ection coefficients for s- and p-polarizations within the considered spectral region (460–580 nm) is less than 1%.
