Patent ·
OSTI ID:7146930

This patent describes a dish reflector for concentrating solar flux uniformly over a target plane on a solar cell array. It comprises: a plurality of concentric, concave, reflective surface elements, arranged symmetrically about a common axis which is perpendicular to the target plane, and each of the surface elements being defined with respect to its axial position forward of a parabolic reference dish sharing the common axis and having a vertex spaced from the target plane by a distance equal to the focal length of the reference dish.
