A concentrating solar reflector adapted to focus light on a target positioned and spaced a predetermined distance from said reflector comprising a lens having optical power and a predetermined equivalent focal length, a linear echelon element having parallel prisms defined thereon closely positioned

A concentrating solar reflector adapted to focus light on a target positioned and spaced a predetermined distance from said reflector comprising a lens having optical power and a predetermined equivalent focal length, a linear echelon element having parallel prisms defined thereon closely positioned to said lens, and a mirror surface, said lens, said echelon element and said mirror surface having an optical axis and being so arranged that light entering said lens and said echelon element is refracted and reflected back through said lens to said target for a given angle of incidence of light rays thereon, said echelon element being angularly positioned with respect to the optical axis such that said prisms refract and said mirror surface reflects to said target for a predetermined angle of incidence of solar rays on said solar reflector, said target being positioned above said reflector.
