This paper describes catadioptric Fresnel lenses of a single lens material that are free of longitudinal chromatic aberration at all transmitted wavelengths. The design requirements for both convergent and divergent achromatic singlet catadioptric Fresnel lenses are given. A positive achromatic catadioptric doublet, consisting of divergent and convergent catadioptric Fresnel lens elements, is discussed. These microstructured lenses are analyzed using a newly developed non-sequential ray tracing program. An off-axis catadioptric Fresnel lens, for use as a high-aperture light collection system, has been replicated in optical acrylic plastic.
