    Abstract: A correction device for a charged particle beam device for decreasing, correcting or inverting (that is adjusting) the spherical aberration of a charged particle beam is described. The correction principle is similar to that of common multipole-Correctors. But unlike common devices of that kind this new correction device gets along entirely with plane apertures having specially shaped holes in order to supply the multipoles required for correction and is therefore predestined for miniaturization and the use in multi column devices.

    Abstract: The invention provides a lens system for a plurality of charged particle beams. Therein, at least one common excitation coil for at least two lens modules is provided. The lens modules comprise an first pole piece, a second pole piece and at least one opening for a charged particle beam. The lens modules constitute a component and share the excitation coil. Thereby, raw material availability, processing of work pieces and symmetry conditions for the lens fields are improved.
