A radiant energy collecting apparatus for collecting and concentrating solar energy having a primary parabolic reflector which focuses the sun's rays on a focal line and has a principal axis passing through the focal line and a secondary concentrating assembly located adjacent the focal line of the primary reflector. The secondary concentrating assembly, includes a pair of planar reflectors arranged on opposite sides of the principle axis of the primary reflector and a series of secondary parabolic reflectors between the planar reflectors, the secondary parabolic reflectors having focal lines which extend normal to the planar reflectors and to the principal axis of the primary reflector. The secondary reflectors are mounted for rotation about their focal lines and concentrate energy on targets extending along their focal lines.
