Abstract:
A microlithographic projection exposure apparatus ( 10 ) includes a projection lens ( 26 ) that images an object field ( 22 ) arranged in a mask plane ( 24 ) onto a substrate ( 28 ) during exposure operation of the projection exposure apparatus, and an illumination system ( 16 ) that has: an exposure illumination beam path ( 44 ) for radiating illumination radiation ( 14 ) onto the object field on the illumination side with respect to the mask plane, a measurement illumination beam path ( 48 ) for irradiating a measurement structure ( 54 ) arranged in the mask plane with the illumination radiation, and a scattering structure ( 50 ) arranged on the illumination side with respect to the mask plane and outside the exposure illumination beam path. The measurement illumination beam path extends via the scattering structure and runs rectilinearly between the scattering structure and the mask plane.

Claim (Index 9):
Microlithographic projection exposure apparatus according to  claim 8 ,\n wherein, in the exposure position, the at least one part of the illumination radiation is directed onto the object field by the adjustable mirror element via a first mirror element of the further facet mirror arranged in the pupil plane and, wherein, in the measurement position, the beam path directed onto the scattering structure extends via a further mirror element of the further facet mirror.
