Zusammenfassung: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.
