摘要： The invention concerns an optical system for a microlithographic projection exposure apparatus and a microlithographic exposure method. In an embodiment an optical system for a microlithographic projection exposure apparatus includes at least one mirror arrangement (200, 720, 730, 920) having a plurality of mirror elements (200a, 200b, 200c, 721, 722, 733, 731, 732, 733,...) which are displaceable independently of each other for altering an angular distribution of the light reflected by the mirror arrangement (200, 720, 730, 920), and at least one manipulator (300, 720, 910) which is arranged downstream of said mirror arrangement (200, 720, 730, 920) in the light propagation direction and has a raster arrangement of manipulator elements (301, 302,..., 600, 721, 722, 723,... ) in such a way that light incident on the manipulator (300, 600, 720, 910) in operation of the optical system is influenced differently in its polarisation state and/or in its intensity in dependence on the incidence location, wherein at least two mutually different illumination settings (420, 520) are adjustable by the variation in an angular distribution of the light reflected by the mirror arrangement (200), wherein said illumination settings (420, 520) differ from each other in that identical regions of a pupil plane of the illumination system (10) are illuminated with light of a different polarisation state.
