PCT No. PCT/DE80/00001 Sec. 371 Date Oct. 23, 1980 Sec. 102(e) Date Oct. 6, 1980 PCT Filed Jan. 10, 1980 PCT Pub. No. WO80/01751 PCT Pub. Date Sep. 4, 1980.A device for the fine adjustment in all three directions in space of an instrument arranged on a base by means of an actuating member. The actuating member consists of a handle the turning of which acts, via a universal joint, on the parts of the base adapted to provide vertical displacement of the instrument, and of an inner lever which when moved around the pivot point defined by the universal joint effects the horizontal displacement of the instrument with respect to a base plate. The inner lever is swingable towards all sides in a sleeve firmly connected with the base and its lower end is adapted with a ball foot which rests directly on the base plate. The bearing sleeve of the inner lever is arranged in or near the plane of the cardan joint; the radius of the ball foot corresponds to the distance between the bearing sleeve and the base plate.
