Abstract:
A projection objective of a microlithographic projection exposure apparatus contains a plurality of optical elements arranged in N>−2 successive sections A 1  to A N  of the projection objective which are separated from one another by pupil planes or intermediate image planes. According to the invention, in order to correct a wavefront deformation, at least two optical elements each have an optically active surface locally reprocessed aspherically. A first optical element is in this case arranged in one section A j , j=1 . . . N and a second optical element is arranged in another section A k , k=1 . . . N, the magnitude difference |k−j| being an odd number.

Claim (Index 11):
The catadioptric projection objective of  claim 9 , wherein the first and second corrective structures are positioned relative to each other so their combined effect is to reduce one or more imaging errors of the projection objective at the second field plane relative to the initial arrangement.
