摘要： A positioning device is provided with a spindle and a spindle nut cooperating therewith for the conversion of a rotary motion into a linear motion for a coarse adjustment, and a piezoelectric linear positioning element arranged in series with the spindle and spindle nut for fine adjustment. The piezoelectric linear positioning element is relieved of transverse forces and moments by a cardan joint that is arranged between an object seating and the spindle.

摘要： A rotary bearing, in particular for optical measuring technology, such as measuring the image fidelity of an optical element, with an aperture and central axis, is provided with an outer mounting part (1) and with an inner bearing part (2). The inner bearing part (2) is connected to a drive output part (6), which can be rotated with respect to the outer mounting part (1) about the central axis. The outer mounting part (1) and the inner bearing part (2) lie in a common plane and are interconnected by articulated joints. The inner bearing part (2) is divided into a plurality of segments, which are respectively connected to the drive output part (6) via resilient articulated joints.
