Abstract:
The disclosure relates to an optical system of a microlithographic projection exposure apparatus or of a wafer inspection apparatus having a first retardation manipulator, a second retardation manipulator, and a manipulator for displacing the second retardation manipulator independently of the first retardation manipulator in at least one direction that is transverse to the optical system axis of the optical system. The second retardation manipulator leaves the wavefront of light that passes through it during operation of the optical system unchanged. In a specified starting position of the first retardation manipulator and of the second retardation manipulator, the sum of the retardations caused by the first retardation manipulator and the second retardation manipulator coincides for all rays that travel parallel to the optical system axis during operation of the optical system.

Claim (Index 10):
The optical system of  claim 6 , wherein, for each of the first and second retardation manipulators, one the partial elements comprises optically uniaxial crystal material with an orientation of the optic axis that is perpendicular to the optical system axis.
