Paper Abstract

Analytical expressions for the photon radiance and its derivative in the spectral band from 400 to 700 microns are presented in a graphic form as a function of temperature for the cryogenic temperatures from 1 to 8 K. The temperature dependence of photon radiance and its derivative have been applied to a background-limited telescope to determine the temperature tolerances. It is concluded that the application of the background-limited telescope operation concept to the telescope operational requirements results in a reduction in the telescope temperature, i.e., an increase in temperatures for the most components, and a prolonged telescope facility lifetime.
