4. MICROSCOPE HANDLING
4.1 Interpupillary Distance Adjustment
Before adjusting the interpupillary distance, bring a specimen into focus using the 10x objective.
Adjust the interpupillary distance so that both the right and left field of view become one (Fig.11).
This adjustment will enable the user to observe the specimen with both eyes.
(Fig.11)
4.2 Diopter
Adjustment
Diopter adjustment compensates for the differences in vision between the left and right eyes. In addition
to making observation through both eyes easier, this adjustment also reduces the
extent to which focusing is lost when the objective magnification is changed. In particular, this occurs
when a low magnification objective is used.
Set the diopter on both eyepieces to the “0” position.
Swing in the 10x objective, focus with one eye only (as everybody has got a “strong” eye, use this
one for this first focussing).
When in focus, close this eye and use the other one.
Focus by only
using the diopter ring (Fig.12) on the
respective eyepiece, do not use the coarse/ fine knob!
Change to a higher magnification and repeat the
above procedure as needs.
As the focus depth is less in high magnification
lenses, a precise adjustment of the diopters here is
easier. Keep this final diopter position for all lenses.
