A raster arrangement includes at least one raster element of a first type and at least one raster element of a second type. Each raster element of the first type has a first bundle-influencing effect. Each raster element of the second type has a second bundle-influencing effect which is different from the first bundle-influencing effect. Each raster element of the first type is located in a first area of the raster arrangement. Each raster element of the second type is located in a second area of the raster arrangement which is different from the first area of the raster arrangement.

Illumination system for microlithography

A microlithography illumination system includes a first raster arrangement including a first plurality of bundle-forming raster elements arranged in or adjacent a first plane of the illumination system. The first plurality of bundle-forming raster elements is configured to generate a raster arrangement of secondary light sources. The illumination system also includes a transmission optics configured to superimpose transmission of the illumination light of the secondary light sources into the object field. The transmission optics includes a second raster arrangement comprising a second plurality of bundle-forming raster elements. The illumination system further includes a displacement device configured to displace a displaceable segment of the first raster arrangement relative to the second raster arrangement. The displaceable segment includes exactly one of the raster elements, a group of several raster elements, a raster column, a raster area, or several groups of raster elements.

A raster arrangement includes first and second types of raster elements which have different bundle-influencing effects. There is a distance step between a first raster area and a second raster area. The first raster area comprises a raster element of the first raster element type. The second raster area includes a raster element of the second raster element type. The raster arrangement is configured to be used in a microlithography illumination system.

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 (&#x394;, &#x394;, &#x394;) 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.
