Paper Abstract

The report describes the development and optimization of optical scheme of the illumination optics of the entrance slit for the high-resolution fiber-fed echelle-spectrograph. The optical system of the illuminator provides the necessary agreement of the numerical apertures of the fiber and spectrograph, as well as it allows to install the necessary equipment to obtain the required structure of the image. As a result of the designing two components illumination system was obtained, which has a good transmission in a specified spectral range and low cost. This research provides a good instrument for performing modern researches for the astronomy.
