The optical layout of the T-170M telescope for observation of astronomical objects in the ultraviolet spectral range 0.115-0.35 μm from the spacecraft SPECTRUM-UV is described. The telescope represents a Ritchey-Chretien aplanat with an aperture 1.7 m in diameter, a relative hole of f/10, and a field of view of 0.5°. The spectrographs are designated for obtaining spectra of stars and spread objects with a resolution of 2000-50 000. It is planned to record direct images using two field cameras: a wide-angle ( f/10) and a telefocus ( f/75- f/100) camera. The tolerances for basic parameters and the characteristics of the optimal system of baffles and the optics control unit are given.
