Combination of focusing and apodization in one multilevel diffractive lens

Abstract

We show that both the functions of focusing and apodization can be simultaneously realized by one multilevel diffractive lens. As an example, we numerically design an 8-phase-level diffractive lens to produce a Gaussian focal spot.
