Adjusting the interpupillary distance

The adjustment of the interpupillary distance is to adjust the distance
between two eyepieces to fit to the distance between your two eyes.
By doing so, you can see the single microscope image so that the
fatigue of your eyes during observation can be reduced.

While setting the right and left eyepieces in parallel, move the binocular
in the a or b direction until the right and left fields of view coincide
completely. The number shown by the indicator ( ) of the left side
eyepiece sleeve is the interpupillary distance.
Remember your interpupillary distance so that you can adjust
