title: Monochromatic primary aberrations of a diffractive lens on a finite substrate.
abstract: This paper presents convenient expressions for the monochromatic primary aberrations of a diffractive lens on a spherical substrate having a nonunity refractive index. Sets of nomographs that provide ready estimates for these aberrations are also given. This analysis facilitates structural design of diffractive lenses in various applications-where they are used as stand-alone devices or as one or more components in a multicomponent system.
