An incident radiation absorber/reflector assembly having a mounting housing to which is adjustably secured an absorber body and a reflector element. An entrance opening, aligned with the reflector element, is formed within the body. The entrance opening is connected to a cylindrical cavity within the body by a tapered passageway which is offset from the longitudinal axis of the cavity. Any incident radiation intercepted by the reflector element is directed by the reflector element into the cavity where it is substantially absorbed by the absorber body.
