The stage has vernier scale graduations in both X and Y axes. A third scale and vernier was added for recording the position of the movable 'check-piece' or slide holder, which secures the position of the left side of the slide. The right side slide holder also slides in the same groove. This allows the X and Y verniers to then be used as a 'finder' to locate a specific spot on the slide repeatedly. This stage also has rotational motion, with a locking screw knob.
The rotating stage also has two centering screws with milled knobs.
Side Refine Panel
There is also a small lever to lock the mechanical stage forward and backward motion, a feature especially useful when the stand is inclined or even horizontal. Another stage, the 'Photomicrographic Stage' also shown for comparison on the Zeiss Stage Page was also offered as an option; this stage had a different kind of adjustment which assumed gross positioning of the slide by hand, and then only a fine adjustment via controls to allow the object to be carefully positioned for photography.
This stand could also be provided with a rotating, but otherwise plain vulcanite stage with stage clips. The substage has diagonal rack and pinion height adjustment.
This example is equipped with the Abbe Swing-out Condenser, a plain condenser also being offered. The condenser apparatus currently on this microscope has only one iris diaphragm, below the condenser fitting. This iris can rotate, and via a small diagonal rack and pinion, be offset from center to allow variations in indirect illumination.

The iris and the optical component condenser can be swung out of the optical axis separately as desired. The fitting that holds the condenser then remains in place to accept other accessories as desired. The microscope has a graduated draw-tube which is graduated from 14 to 19 cm by 1 mm. There is no stop to hold it in fully extended, making substitution of the Bitumi binocular head simple.
