Abstract A design of a reflection holographic lens with nonspherical wavefront is described, which is based on a ray-tracing program and a simple search algorithm suitable for a microcomputer. The optimized wavefront is encoded into a computer- generated hologram (CGH). The reflection holographic lens with the optimum wavefront produced by CGH reduces the rms spot radius at large field angles, and allows for a compact folded system and for Bragg diffraction into a single order. Experimental results are shown. Helpful data on the diffraction efficiency and the spectrally diffracted intensity of reflection holograms are presented.
