Abstract

An optical imaging device, particularly an objective, is provided with at least one optical element, which is mounted in an inner ring, the inner ring being connected to an outer mount. A manipulator device serves for the displacement of the optical element in at least one direction that is perpendicular to the optical axis. By a system of peripheral slots between the inner ring and the outer mount with connecting members situated therebetween, a rotary joint between the inner ring and the outer mount, and at least one displacing rotary joint with an adjusting member between the inner ring and the outer mount as the manipulator device, a displacement of the optical element is attained with low deformation or controlled deformation of the optical element. The inner ring and the outer mount are preferably constituted monolithically.
