The paper briefly describes the goals and objectives of the planned space experiment "Sun-Terahertz" aboard the Russian Segment of the ISS. The experiment is aimed at studying solar radiation in the unexplored terahertz range at frequencies of 1012...1013 Hz, obtaining new data on terahertz radiation from the sun, solar active regions and solar flares. The main components of the optical path of scientific equipment are considered. With the help of the Blackbody Simulator and the Single-Channel Model, the detectors of scientific equipment were calibrated, the influence of the quality of the optical surface of the telescope mirrors on the detector signal amplitude in the terahertz range was studied, and a preliminary assessment of the detector sensitivity was carried out. Keywords: Sun, solar flares, terahertz radiation, optical system.
