Abstract:
A microlithographic projection exposure apparatus optical 22 system includes a first reflective surface and at least one second reflective surface, each in the optical beam path. The first reflective surface is movable for the correction of an aberration that occurs during the operation of the optical system. The optical system is configured in so that, during the travel movement of the first reflective surface, the relative position of the first reflective surface and of the second reflective surface is maintainable in a stable manner. Either the first reflective surface and the second reflective surface directly succeed one another in the optical beam path, or there are only reflective optical elements between the first reflective surface and the second reflective surface.

Claim (Index 1):
An optical system having an optical beam path, the optical system comprising:\n a first mirror body supporting a first reflective surface; and a second mirror body supporting a second reflective surface, wherein:\n the first mirror body is different from the second mirror body; \n the first reflective surface is in the optical beam path; \n the first reflective surface configured to move to an aberration that occurring during operation of the optical system; \n the second reflective surface is in the optical beam path; \n the optical system is configured so that, during movement of the first reflective surface, a relative position of the first and second reflective surfaces is maintained in a stable manner; and \n along the optical path, one of the following holds:\n there are no reflective surfaces between the first and second reflective surfaces; and \n only reflective optical elements are between the first and second reflective surfaces.
