Abstract
It is provided a charged particle beam manipulation device for a plurality of charged particle beamlets, the charged particle beam manipulation device including a lens having a main optical axis, the lens including at least a first array of multipoles, each multipole of the first array of multipoles configured to compensate for a lens deflection force on a respective charged particle beamlet of the plurality of charged particle beamlets, the lens deflection force being a deflection force produced by the lens on the respective charged particle beamlet towards the main optical axis of the lens.
