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 right eye and
bring the image into focus in your left eye with the
coarse/fine focus control
. Once the image is well-focused using only
your left eye, close your left eye and check the focus with your right. If the image is not perfectly focused, make fine
adjustments with the
diopter adjustment mechanism
located on the right eyetube (see figure 12). Once complete, the
microscope is corrected for your vision.

The 100X
objective
which comes with this microscope must be used with immersion oil in order to maintain image quality.
After use, the objective tip needs to be wiped clean so that no oil residue remains.
Procedure for cleaning the 100X Oil Immersion Objective:
Lightly moisten a cotton swab with lens cleaner.
Wipe the objective with a twisting motion in order to remove all traces of the immersion oil.
Check that all the immersion oil has been removed before storing the objective.
Under no circumstances should an oil immersion objective be left sitting in oil for an extended period of time. Exceptionally
long immersion periods can cause oil to penetrate the objective’s sealant and obscure the optics, which is not covered under
warranty.
