Diopter adjustment
Adjust the fine focusing knob
to get the image sharp and
clear while observing with
your right eye, then turn the
left diopter ring to a sharp
and clear image also with the
other eye. The highpoint eye-
pieces allow the user to wear
glasses. (Fig.15)
NOTE :For the optimal para-
focality of the image, it's sug-
gested to wear your glasses
during the normal use of the
microscope.
Centering the
condenser
Insert the swing-out lens of
the condenser ① and fully clo-
se the field diaphragm ②. Ro-
tate the condenser adjustment
knob ③ until you see a sharp
image of the closed field
diaphragm (a bright spot of
light). Act on the condenser
centering screws ④ until you
move the bright spot in the
center of the image field. Then
re-open the field diaphragm
②. (Fig.16)
Adjust the aperture of the iris
diaphragm under the conden-
ser to set the numerical aper-
ture of the illuminator, thus
controlling image contrast and
resolution. It is suggested to
set the aperture diaphragm
between 70% and 80% of
objective's N.A. (Fig.17)
