摘要:
A catadioptric objective comprises a plurality of lenses and at least two deflecting mirrors that have reflecting surfaces that are at a specific angle, in particular of 90°, to one another. The two deflecting mirrors are arranged with their reflecting surfaces on a common base member whose position in the objective can be set.
