Abstract
A universal revolving stage for microscopes having glass segments mounted in an upper and a lower segment mountings serves in particular to conduct crystal-optical investigations. Because of the differential thickness of the specimens to be examined, there is provided a height adjustment of the segment mountings by means of adjusting means actuated from above, in the form of a pinion. The adjusting means is rotated by a knurled knob which can be inserted into it, and it engages the internal teeth of an adjusting ring which has an adjusting thread. Upon rotation of the pinion and thus of the adjusting ring, the lower segment mounting is screwed upwardly or downwardly, and it carries with it the upper segment mounting which is centered by guides in the lower mounting.
