An imaging optics includes a plurality of mirrors which reflect imaging light to image an object field in an object plane into an image field in an image plane. A mirror body of at least one of the mirrors has a through-opening for the imaging light to pass through. The through-opening has an internal region of a smallest opening width in the mirror body. The through-opening expands from the internal region towards both edge regions of the mirror body. A disturbing influence of unused light portions is reduced or eliminated completely.
