Abstract

In this contribution we recognize that it is possible to obtain an achromatized version of a selected Fresnel diffraction pattern of an input transparency, using a single on-axis blazed zone plate. The input is illuminated by a polychromatic converging spherical beam and the zone plate is inserted at the source plane. In this optical configuration, the position of the input transparency along the optical axis permits to select the Fresnel diffrac- tion field to be achromatized. In this way, we are able to record, at finite distances, a wide range of diffraction patterns with a low chromatic aberration over the entire visible spectrum.
