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 15):
The catadioptric projection objective of  claim 9 , wherein the plurality of optical elements comprises a third lens comprising a surface having a third corrective structure that is in the path of the light.
