Abstract

An optical lens fixture 10 has three adjusting screws 11 mounted with angular symmetry in threaded blocks 12. Spring-actuated ball plungers 13 are mounted on the ends 14 of each screw 11. By adjusting the screws 11 in blocks 12, the lens frame or tube T is precisely located in the XY plane. Ball plungers 13 allow for zero clearance and also provide vibration damping for the lens L mounted in tube T. The ball surfaces of plungers 13 provide axial loading and thus only a relatively small force is required to rotate, angulate, i.e. tilt, and/or otherwise vertically position the tube T relative to the XY plane.
