Abstract
We present a complete theory for purely diffractive doublets corrected at two wavelengths. First we describe a class of diffractive doublets that can accomplish real imaging from one object point to one image point in two colors. The paraxial model of the design is also presented. Then we evaluate the performance of this class of doublets, comparing them with refractive singlets, hybrid (refractive–diffractive) singlets, and diffractive doublets based on Fresnel phase lenses. The class has a usable bandwidth that is approximately an order of magnitude better than the conventional Fresnel design.
