3.7 Operating the Condenser
3.7.1 Focusing the Condenser
Adjust the vertical position of the condenser so that the field
diaphragm image is clearly visible in the field of view.
Caution: Do not raise the condenser too much.
If you raise the condenser too much, the condenser lens
might hit the specimen's glass slide, causing damage to
the condenser lens or the glass slide.
When raising or lowering the condenser lens, be careful
not to hit the specimen's glass slide.

3.7.2 Centering the Condenser
Adjust the position of the condenser so that the illumination
is correctly centered in the field of view. This operation is
called “centering the condenser.”
You can adjust the position of the condenser by turning the
condenser centering knobs on each side of the aperture
diaphragm lever.
Adjusting the position of the condenser
Bring the 10x objective into the optical path, narrow the field
of view, and adjust the position of the condenser so that the
field diaphragm image is centered in the field of view.
When performing strict position adjustment, bring a
higher-magnification objective into the optical path and
perform centering as usual.
