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 23):
A microlithographic projection exposure apparatus, comprising:\n the catadioptric projection objective of claim  1 ; and an illumination device, which during operation, generates light for illuminating the reticle positioned in the first field plane.
