A cylindrical radiant energy collector is provided which includes a reflector spaced apart from an energy absorber. The reflector is of a particular shape which ideally eliminates gap losses. The reflector includes a plurality of adjacent facets of V shaped segments sloped so as to reflect all energy entering between said absorber and said reflector onto said absorber. The outer arms of each facet are sloped to reflect one type of extremal ray in a line substantially tangent to the lowermost extremity of the energy absorber. The inner arms of the facets are sloped to reflect onto the absorber all rays either falling directly thereon or as a result of reflection from an outer arm.

DETAILED DESCRIPTION A device is provided for reflecting radiant energy incident thereon onto the surface of an energy absorber.
The device is positioned spaced apart from the absorber and includes a plurality of adjacent facets or V-shaped segments which insure that the incident energy within a given range is not reflected out through the gap formed between the device and the absorber.
The form and angle of the V-shaped segments is particularly defined.
