摘要:
A microlithographic projection exposure apparatus comprises a projection objective which images an object onto an image plane and has a lens with a curved surface. In the projection objective there is a liquid or solid medium which directly adjoins the curved surface over a region which is usable for imaging the object. The projection exposure apparatus also has an adjustable manipulator for reducing an image field curvature which is caused by heating of the medium during the projection operation.
