Spectrograph design for astronomical telescopes

Abstract

Many astronomy studies are based on spectral measurements of the stars and heavenly bodies. In this paper, high-resolution spectrograph is designed to be used in the large astronomical telescope. By adding this system, the best use of large astronomical telescope such as national telescope change can be done. Spectrograph slit can be placed in the focal plane of astronomical telescope or the focused beam transferred with an optical system from the focal plane to the slit of spectrograph.
