摘要： A catadioptric projection objective for imaging of a pattern, which is arranged on the object plane of the projection objective, on the image plane of the projection objective has a first objective part for imaging of an object field to form a first real intermediate image, a second objective part for production of a second real intermediate image using the radiation coming from the first objective part; and a third objective part for imaging of the second real intermediate image on the image plane. The second objective part is a catadioptric objective part with a concave mirror. A first folding mirror for deflection of the radiation coming from the object plane in the direction of the concave mirror and a second folding mirror for deflection of the radiation coming from the concave mirror in the direction of the image plane are provided. A field lens with a positive refractive power is arranged between the first intermediate image and/or the first folding mirror and the concave mirror, in an area close to the field of the first intermediate image.

The mirror group entry is positioned in a region where radiation exiting the front lens group has an entry chief ray height. A second reflecting area is positioned in a region where radiation impinging on the second mirror has a second chief ray height deviating from the entry chief ray height in a first direction; and a fourth reflecting area is positioned in a region where radiation impinging on the fourth mirror has a fourth chief ray height deviating from the entry chief ray height in a second direction opposite to the first direction.

摘要： Ein optisches Abbildungssystem für eine Mikrolithographie-Projektionsbelichtungsanlage dient zur Abbildung eines in einer Objekt-ebene des Abbildungssystems angeordneten Objektfeldes in ein in einer Bildebene des Abbildungssystems angeordnetes Bildfeld. Es kann sich insbesondere um ein Projektionsobjektiv oder um ein im Beleuchtungs-system einzusetzendes Relais-Objektiv handeln. Das Abbildungssystem hat eine Vielzahl von Linsen, die zwischen der Objektebene und der Bildebene angeordnet sind und jeweils eine erste Linsenfläche und eine zweite Linsenfläche aufweisen. Mindestens eine der Linsen ist eine Doppelasphärenlinse, bei der die erste Linsenfläche und die zweite Lin-senfläche eine asphärische Fläche ist. Bei Doppelasphärenlinsen ist es möglich, mit vertretbarem Aufwand bei der Oberflächenbearbeitung und Prüfung der Linsenoberflächen Linsen mit guter Qualität herzustellen, die die Wirkung einer Asphäre mit sehr starker Deformation haben.
