ABSTRACT:
A structural member for use in a telescope or the like comprises an inner member of a structural material imparting rigidity and strength, an intermediate layer of a heat-insulating material, and an outer layer having a low emissivity and low heat capacity. The outer layer is able to quickly follow changes in outside air temperature, while the intermediate layer of insulating material reduces the propagation of heat between the outer layer and the inner structural material, thereby avoiding rapid temperature variation of the structural material.
