The invention relates to a low temperature optical system support device with high heat insulation efficiency and small thermal stress influence. In the device, a support inner ring is fixedly connected with a second heat insulation ring through three second support blocks which are uniformly distributed at the periphery of the support inner ring; the second heat insulation ring is fixedly connected with a first heat insulation ring through three transition blocks which are uniformly distributed at the periphery of the second heat insulation ring; and the first heat insulation ring is fixedlyconnected with a support outer ring through three first support blocks which are uniformly distributed at the periphery of the support outer ring. By the support device with a dual glass reinforced plastic annular structural form, a heat conduction path is prolonged, the thermal resistance between a high temperature end and a low temperature end is increased, and the heat insulation efficiency ofthe component is greatly i
