    摘要： An illumination system for microlithography serves to illuminate an illumination field with illumination light of a primary light source. A first raster arrangement has bundle-forming first raster elements which are arranged in a first plane of the illumination system or adjacent to the plane. The first raster arrangement serves to generate a raster arrangement of secondary light sources. A transmission optics serves for superimposed transmission of the illumination light of the secondary light sources into the illumination field. The transmission optics has a second raster arrangement with bundle-forming second raster elements. In each case one of the raster elements of the first raster arrangement is allocated to one of the raster elements of the second raster arrangement for guiding a partial bundle of an entire bundle of illumination light. The first raster arrangement for example has at least two types (I, II, III) of the first raster elements which have different bundle-influencing effects. The raster elements of the two raster arrangements are arranged relative to one another in such a way that to each raster element type (I to III) is allocated at least one individual distance (ΔI, ΔII, ΔIII) between the first raster element of this type (I to III) and the allocated second raster element of the second raster arrangement. As a result, an illumination system is obtained which allows particular illumination parameters to be influenced in such a way that undesirable influences on other illumination parameters are avoided to the greatest extent possible.
