The far infrared telescope with 1meter metallic primary mirror is proposed as the possible candidate for Submillimetron Mission realisation. The optical scheme and main characteristics of the telescope are presented. The opportunity of active cooling of the main mirror by the closed loop refrigerator for long - life observations is discussed. The scheme of the tests in the vacuum chamber to check the thermal deformation of the main mirror is considered.
