Abstract
An apparatus for inspecting a sample includes a sample holder for holding the sample; a multi beam charged particle generator for generating an array of primary charged particle beams; an electro-magnetic lens system for directing the array of primary charged particle beams into an array of separate focused primary charged particle beams on the sample; a multi-pixel photon detector arranged for detecting photons created by the focused primary charged particle beams when the primary charged particle beams impinge on the sample or after transmission of said primary charged particle beams through the sample; and an optical assembly for conveying photons created by at least two adjacent focused primary charged particle beams of the array of separate focused primary charged particle beams to distinct and/or separate pixels or to distinct and/or separate groups of pixels of the multi-pixel photon detector.
