Abstract:
A projection lens ( 50 ) for a microlithographic projection exposure apparatus ( 10 ) includes a plurality of optical elements (M 1 -M 8 ) for imaging mask structures ( 28 ) onto a surface ( 34 ) of a substrate ( 36 ) by way of projecting the mask structures using imaging radiation ( 14 ) that travels along a used beam path. At least one of the optical elements (M 8 ) is formed with an opening ( 56 ) and the projection lens has a measurement beam path ( 66 ) extending through the opening.

Claim (Index 1):
A device comprising a projection lens for a microlithographic projection exposure apparatus and a measurement apparatus configured to measure a property of the projection lens, wherein the projection lens comprises a plurality of optical elements for imaging mask structures onto a surface of a substrate by projecting the mask structures with imaging radiation that travels along a used beam path, wherein at least one of the optical elements comprises an opening, and wherein a measurement beam path extends through the opening.
