Abstract
An apparatus for obtaining radiant energy has first and second photovoltaic receivers. A primary curved reflective surface is disposed to reflect incident polychromatic radiation toward a first focal plane. A spectral separator is disposed between the first focal plane and the primary curved reflective surface. The spectral separator has a dichroic separating surface, convex with respect to the incident reflected polychromatic radiation and treated to reflect a first spectral band toward the first photovoltaic receiver and to transmit reflected polychromatic radiation outside the first spectral band. The spectral separator also has a curved separator reflective surface, convex with respect to the light transmitted through the dichroic separating surface and treated to reflect at least a portion of the light transmitted through the dichroic separating surface toward the second photovoltaic receiver.
