摘要： A projection exposure system for microlithography comprises at least one optical system, for example a lithography lens comprising at least one bi-asphere (1) with two aspheres (2,3). In accordance with the invention, the projection exposure system has a manipulator which compensates tilting of the aspherical axes A2, A3 of the two aspheres (2,3) by tilting bi-asphere (1) about two mutually perpendicular axes RX and RY such that the projection properties of the optical system are optimized. In addition, a centering manipulator can be provided that executes translations TX and TY for the purpose of aligning the axes A2 and A3 with respect to the optical axis OA. With the aid of the inventive system, it is possible, with the bi-asphere (1) already mounted at the lens, using the projection parameters from the system itself, to perform an alignment of the lens (1), in particular tilting, for the purpose of optimizing the projection parameters of the lithography lens.
