Abstract

A phase-shifting element for shifting a phase of at least a portion of a particle beam is described, as well as a article beam device having a phase-shifting element of this type. In the phase-shifting element and the particle beam device having a phase-shifting element, components shadowing the particle beam are avoided, so that proper information content is achieved and in which the phase contrast is essentially spatial frequency-independent. The phase-shifting element may have at least one means for generating a non-homogeneous or anisotropic potential. The particle beam device according to the system described herein may be provided with the phase-shifting element.
