We present an optical and thermal design of one of major instrumental payload planned for SOLAR-C mission/Plan-B (high resolution spectroscopic option): the telescope assembly of Solar Ultra-violet Visible and near IR observing Telescope (SUVIT). To accommodate a launcher's nosecone size, a wide observing wavelength coverage from UV (down to 280 nm) through near IR (up to 1100 nm), and an 0.1 arcsec resolution in the field of 200 arcsec diameter, a short telescope design was made for a 1.5 m aperture solar Gregorian telescope with the compact design of three-mirror collimator unit.
