Abstract
A mechanism, for adjusting the position of an illuminating lamp longitudinally and angularly in planes perpendicular to the optical axis of the condenser, has a lead screw and guide rod mounted substantially parallel to each other on the housing. The lamp socket holder is longitudinally traversed by the lead screw and the guide rod is eccentrically adjusted to impart a tilting movement to the holder. Control knobs for the lead screw and tilting mechanism are disposed adjacent each other on the outside of the housing. The lamp socket may also be axially and rotatably adjusted in the holder.
