Zusammenfassung:	An optical apparatus for illuminating an object, for example an illumination system of a microlithographic exposure system, comprises a light source that generates a plurality of individual bundles that constitute an illumination bundle. A control device controls the light source in such a way that a desired form of the illumination bundle is determined by selecting an appropriate set of individual bundles.
