Adjusting the aperture diaphragm
The aperture diaphragm is a diaphragm to adjust the numerical aperture
of the condenser.
Adjusting the numerical aperture of the condenser appropriately with
respect to the numerical aperture of each objective allows you to observe
the specimen with the best contrast and resolution. (For the aperture
diaphragm, see page 31.)
Move the aperture diaphragm lever
a
to right and left direction to
match with the numerical aperture (NA) of the objective in use.
For darkfield observation, fully open the aperture
diaphragm.
If you want to fix the aperture diaphragm at the desired
position, rotate the aperture diaphragm fixing knob
b
at the
back of the condenser in the arrow direction to fix the aperture
diaphragm.
