Zusammenfassung:	An apparatus for obtaining energy from a polychromatic radiant energy source has a light concentrator for concentrating and redirecting incident radiant energy, having an optical axis, and a spectral separator disposed along the optical axis, apart from the light concentrator and in the path of concentrated, redirected radiant energy. The spectral separator has a first planar surface treated to reflect a first spectral band of light toward a first focal region and to transmit a second spectral band and a second planar surface spaced apart from the first planar surface and oblique with respect to the first planar surface. The second planar surface is treated to reflect the second spectral band back through the first planar surface and toward a second focal region spaced apart from the first focal region. First and second light receivers are disposed nearest each respective focal region for receiving the first and second spectral bands.
