Abstract: A beam distribution apparatus includes a stack of parallelogram prisms and beam-splitting coatings each located between opposing parallel faces of adjacent parallelogram prisms. The stack is mounted on an entrance face of a triangular prism. The triangular prism includes the entrance face, a reflective face, and an exit face. The reflective face has optical surfaces for shaping output beams from the stack and reflecting the output beams through the exit face. A beam distribution apparatus includes a stack of parallelogram prisms and beam-splitting coatings each located between opposing parallel faces of adjacent parallelogram prisms in the stack. The beam-splitting coatings transmit light of a first polarization and reflect a portion of light of a second polarization. The apparatus further includes retardation plates each mounted on a face of a parallelogram prism adjacent to a beam-splitting coating, and corrective reflective optics for shaping output beams each mounted on a retardation plate.
