This paper discusses the possibility of constructing high-quality images in a system consisting of a telescope with a nonflat focal surface and a flat detector. As an example, the approach that is used when creating the large extra-atmospheric UV observatory, Spectrum-UV, is described. It is shown that the optical system can be optimized in such a way that high image quality is achieved with realistic sizes of the flat detector. The effect of thermal strains of the primary mirror of the T-170M telescope of the Spectrum-UV observatory on the image quality is also considered. It is shown that these strains need not be taken into account when optimizing the optical system consisting of the telescope and the focal-device unit.
