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 3):
The device according to  claim 1 ,\n wherein the measurement apparatus is configured to orient the measurement beam path at the site of the opening to be tilted by at least 1\u00b0 with respect to the used beam path.
