    摘要: A method for improving imaging properties of two or more optical elements comprises the step of determining for at least one of the two optical elements a polarization-dependent perturbation. In a further step a polarization-independent perturbation is determined for at least one of the two optical elements. Then a target position for the at least one movable optical element is calculated such that, in the target position, the total perturbation of the at least two optical elements which is made up of the polarization-dependent perturbations and polarization-independent perturbations of the two optical elements, is minimized. Finally the at least one movable optical element is moved the to the calculated target position.

    摘要: A projection exposure system and a method for operating a projection exposure system for microlithography with an illumination system are disclosed. The illumination system includes at least one variably adjustable pupil-defining element. The illumination stress of at least one optical element of the projection exposure system is determined automatically in the case of an adjustment of the at least one variably adjustable pupil-defining element. From the automatically determined illumination stress, the maximum radiant power of the light source is set or determined and/or in which an illumination system is provided with which different illumination settings can be made. Usage of the projection exposure system is recorded and, from the history of the usage, at least one state parameter of at least one optical element of the projection exposure system is determined.
