Place the specimen on
the stage
Fix the specimen slide on the
mechanical stage using the
slide-clamp. Ensure that the
specimen is centred over the
stage opening. (Fig.21)
Focus tension
adjustment
Turn the tension-adjust knob
to get a suitable tension for
the focus system. (Fig.22)
NOTE: if the tension is too lo-
ose, the stage could go lower
by itself or the focus easily
lost after fine adjustment. In
this case, rotate the knob in
order to increase the friction.
Focus-stop knob
Loosen the focus-stop knob,
rotate the coarse focusing
knob to bring the slide into
focus with a 4X or 10X objecti-
ve. Then rotate the focus-stop
in order to block the height of
the stage. This simplifies the
next focusing operations.
The focus-stop knob is also
useful to avoid accidental con-
tacts between objective and
specimen. (Fig.23)
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.24)
NOTE :For the optimal para-
focality of the image, it's sug-
gested to wear your glasses
during the normal use of the
microscope.
