Primary chromatic aberrations of a diffractive lens on finite substrate.
In this report, we present an analysis for the primary chromatic aberrations of a diffractive lens on a spherically curved substrate having nonunity refractive index. This analysis facilitates achieving an optimal thin lens layout during structural design of the diffractive lens with prespecified targets for primary chromatic aberrations. Sets of nomographs that provide ready estimates for these aberrations are also given.
