ABSTRACT:
An objective (2) with at least one optical element (4), which is mounted in an inner ring (3). The inner ring (3) is connected to an outer mount (1). A manipulator (10) is provided for displacing the optical element (4) in at least a direction perpendicular to an optical axis. The inner ring (3) is connected to the outer mount (1) by means of at least two adjusting joints (5) with manipulators (10) and at least one swivel joint (6). The at least two adjusting joints (5) and the at least one swivel joint (6) are provided with joint arms (8) extending at least approximately in a tangential direction with respect to the inner ring (3), by means of which arms the inner ring (3) is elastically connected to the outer mount (1). The ends of the joint arms (8) are articulated on the inner ring (3) in such a way that temperature-induced changes in length of the joint arms (8) are converted into a uniform turning direction of the inner ring (3) with respect to the outer mount (1) about the center of the optical element.
