Abstract

The present invention relates to a projection lens assembly module for directing a multitude of charged particle beamlets onto an image plane located in a downstream direction, and a method for assembling such a projection lens assembly. In particular the present invention discloses a modular projection lens assembly with enhanced structural integrity and/or increased placement precision of its most downstream electrode.
