Patent ID: 7193794

Claim:
An adjustment arrangement of an optical element, in particular of a lens in an optical system, the optical system defining an optical axis, the optical element having a circumference and being mounted in a mount by a plurality of bearing feet arranged in a distributed manner over the circumference of the optical element, said bearing feet being formed in an L-shaped manner, the one leg of the bearing foot being connected at its free end to the mount, and a bearing surface for the optical element being arranged in the region of the free end of the other leg, the optical element being selectively deformable by actuators, and at least some of the bearing feet being engaged by at least one actuator in such a way that the respective bearing foot can be displaced in a direction substantially orthogonal to said circumference, wherein each of the bearing feet engaged by one of the actuators has a lever element running in a direction parallel to the optical axis, a bearing surface for the optical element and at least one pivot point, the actuator engaging in the region of the lever element in such a way that the bearing surface can be displaced in the direction of the optical axis, and each of the bearing feet engaged by one of the actuators has two pivot points formed as solid joints, which are arranged at least approximately in the region of a plane in which the centroid of the bearing surface also lies, the one end of the lever element being arranged between the two solid joints, the one solid joint connecting the lever element to the mount and the other solid joint connecting the lever element to the region of the bearing surface, and the actuator engaging the end of the lever element remote from the solid joints.
