Zusammenfassung:	An imaging optics has a plurality of mirrors to image an object field in an object plane into an image field in an image plane. The imaging optics includes a first partial objective to image the object field onto an intermediate image, and the imaging optics includes a second partial objective to image the intermediate image onto the image field. The second partial objective includes a penultimate mirror in the beam path of imaging light between the object field and the image field, and the second partial objective includes a last mirror in the beam path. The penultimate mirror images the intermediate image onto a further intermediate image, and the last mirror images the further intermediate image onto the image field.
