A charged particle beam exposure system has a blanking aperture array (31) having groups of apertures (53) controlled by shift registers (75), wherein different inputs (C) to the shift registers influence a different number of apertures. Charged particle beamlets traversing the apertures are scanned across a charged particle sensitive substrate in synchronism with a clock signal of the shift registers.

A charged particle lithography system comprises a particle source for generating a beam of charged particles, a pattern defining structure and a particle-optical projection system for imaging the pattern defined by the pattern defining structure onto a substrate. The particle-optical projection system comprises a focusing first magnetic lens (403) comprising an outer pole piece (411) having a radial inner end (411'), and an inner pole piece (412) having a lowermost end (412') disposed closest to the radial inner end of the outer pole piece, a gap being formed those; a focusing electrostatic lens (450) having at least a first electrode (451) and a second electrode (452) disposed in a region of the gap; and a controller (C) configured to control a focusing power of the first electrostatic lens based on a signal indicative of a distance of a surface of the substrate from a portion of the first magnetic lens disposed closest to the substrate.

The invention relates to a device for flat illumination of an object field in an optical apparatus and to an optical apparatus having said device, said optical apparatus being, for example, microscopes, including microlithography simulation microscopes, wherein a flat illumination, i.e. extending over a singular object point, of the object to be examined is required. The device comprises a laser light source (8) and a fiber optic cable (9) having at least one optic fiber through which the light is guided from the laser light source (8) to the object field. The optic fiber is configured and designed in such a way that the intensity of the illumination light is increasingly homogenized in the cross section of the optical fiber during its course from the end on the incidence side to the end on the radiation side and the illumination light from the end on the radiation side of optical fiber is directed to the object (O) with substantially homogenous intensity distribution.
