Abstract

This paper is dedicated to method for spectral and polarization selective optical systems properties investigations for accurate analysis of nonclassical diffraction gratings properties: aspherical surfaces, variable grating step, variable line shape, etc. Using the proposed method and algorithm an accurate spectral image and apparatus function of Seya-Namioka diffraction monochromator were calculated. Another advantage of the method is its applicability to spectropolarimeters schema analysis.
