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 16):
A method for measuring a projection lens for a microlithographic projection exposure apparatus, having 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 is formed with an opening, said method comprising radiating measurement radiation that differs from the imaging radiation through the opening of the at least one optical element.
