Setting the Up-Stop Mechanism
The up-stop mechanism is located just inside of the left-hand focus control knob (see figure 10). It allows the user
to set a maximum point to which the stage can be raised, which prevents damage to the specimen and objective.
To set this point, turn the up-stop mechanism in a counterclockwise motion, so that its tab is facing down
(which is also the “no up-stop position” for normal use).
Raise or lower the stage, by turning the focus control knobs, to the desired height. Be careful not to raise the
stage high enough to crash into the objective.
Once achieved, turn the up-stop mechanism in a clockwise motion, so that its tab is facing up (see figure 10).
Once gently tightened, the up-stop mechanism will not allow the stage to be raised higher than the set point.

Interpupillary and Diopter Adjustment

Interpupillary adjustment (the distance between eyepieces) is made through a “folding” action. The Seidentopf
design allows for a folding adjustment which is quickly and easily done for each user (see figure 11).
Diopter adjustment allows for proper optical correction based on each individual’s eyesight. This adjustment
is easily made and is recommended prior to each use by different users to prevent eyestrain.
Using the 40X objective and a sample slide (i.e. one which produces an easily focused image), close your left
eye and bring the image into focus in your right eye with the coarse/fine focus control.
Once the image is well-focused using only your right eye, close your right eye and check the focus with your left.
If the image is not perfectly focused, make fine adjustments with the diopter adjustment mechanism located
on the left eyetube (see figure 12).
Once complete, the microscope is corrected for your vision.
