Beschreibung
Zusammenfassung:	An optical system, in particular for projection-exposure units used in microlithography, in particular with a slot-shaped field of view or non-rotationally symmetrical illumination, has an optical element 1, in particular a lens or a mirror, which is arranged in a mount 7 or an inner ring 2, and actuators 8a, 8b and 9a, 9b. A plurality of actuators 8a, 8b and 9a, 9b act on the deformable inner ring 2 via a radial force-displacement transmission 12, 13 in order to generate tensile and/or compressive forces.
