Abstract
A particle-optical arrangement comprises a charged-particle source for generating a beam of charged particles; a multi-aperture plate arranged in a beam path of the beam of charged particles, wherein the multi-aperture plate has a plurality of apertures formed therein in a predetermined first array pattern, wherein a plurality of charged-particle beamlets is formed from the beam of charged particles downstream of the multi-aperture plate, and wherein a plurality of beam spots is formed in an image plane of the apparatus by the plurality of beamlets, the plurality of beam spots being arranged in a second array pattern; and a particle-optical element for manipulating the beam of charged particles and/or the plurality of beamlets; wherein the first array pattern has a first pattern regularity in a first direction, and the second array pattern has a second pattern regularity in a second direction electron-optically corresponding to the first direction, and wherein the second regularity is higher than the first regularity.
