Abstract:
An imaging optical unit for projection lithography has a plurality of mirrors for guiding imaging light from an object field into an image field. The object field is spanned by a first, larger object field dimension and along a second, smaller object field dimension. The imaging optical unit has at least two GI mirrors and at least one NI mirror. The NI mirror is arranged between two GI mirrors in the imaging light beam path. A used reflection surface of the NI mirror has an aspect ratio between a surface dimension along a first reflection surface coordinate and a surface dimension along a second reflection coordinate parallel to the second object field dimension. The aspect ratio being less than 4.5. An imaging optical unit with reduced production costs emerges.

Claim (Index 3):
The imaging optical unit of  claim 2 , wherein, for each of the first, second and fourth mirrors:\n the mirror has a used reflection surface having a first surface dimension along a first reflection surface coordinate and a second surface dimension along a second reflection surface coordinate parallel to the second object field dimension; and the aspect ratio of the first surface dimension to the second surface dimension is greater than one.
