Non-imaging system for radiant energy flux transformation

Non-imaging system for radiant energy flux transformation comprising:

• an energy concentrator comprising a plurality of non-imaging, facing inward, ring reflective surfaces being coaxially nested with respect to the axis of symmetry of said energy concentrator and having generally concave profiles, said reflective surfaces having larger rims forming an entrance aperture of said energy concentrator and smaller rims forming an exit aperture of the energy concentrator;
• and an energy receiving means located in a target plane on the exit aperture side of the energy concentrator and disposed in energy receiving relation to said reflective surfaces;
• wherein said reflective surfaces are designed and positioned so that opposite supreme off-axis rays emanated from the source of said radiant energy flux and reflected from a rim of at least one of said reflective surfaces strike said target plane at points located at substantially equal distances from the point of intersection of said axis of symmetry and said target plane.
