    摘要: In an oscillation damping system, the oscillations which act on an optical element in an imaging device, in particular on deformation-decoupled mounts and manipulators in a projection illumination arrangement, in particular in a projection objective for microlithographic projection exposure objective lithography, are detected by sensors, by actuators waves with same or at least similar frequencies and amplitudes of anti-phases to the disturbing oscillations are generated and introduced in said mount.

    摘要: In a system for overcoming or at least damping oscillations in or through channels (9) which carry fluid in a component, in particular coolant in cooling channels in an optical element (1), in particular a projection objective lens (1a) for semiconductor lithography, oscillations which occur are detected and evaluated by sensors (5), after which the result is passed, in the form of an adaptronic control loop to piezoelectric elements (9), which are integrated in the optical element, and are in the form of thin plates, films or layers which, when activated, produce the oscillations or frequencies which counteract oscillations and natural frequencies produced by the turbulence.

    摘要: The invention relates to an apparatus for manipulation of an optical element (7) in up to six degrees of freedom with respect to a structure (8) via at least three actuator devices (9). The actuator devices (9) each have at least two force-controlled actuators, which each produce an effective force along one degree of freedom, with linking points (11) of the actuator devices (9) acting directly on the optical element (7).
