Summary: | A lithographic projection system has an illumination system. A plurality of directing elements reflect different sub-beams of an incident projection beam into adjustable, individually controllable directions. By using of re-directing optics any desired spatial intensity distribution of the projection beam can be produced in its cross-sectional plane. |
