OPERATION
4.1
Adjusting the stereo microscope
The stereo microscope has been connected and
switched ON.
1.
Place specimen (Fig. 18/
7
) centrally on the
glass or plastic plate (Fig. 18/
6
) and illuminate
it (Fig. 18/
5
).
The functionality of the knob for the
reflected-light illuminator has been
described in section 4.2 on page 28.
2.
Set diopter compensation on the adjustable
eyepieces (Fig. 18/
1
) to "0".
"0" on white dot (without eyepiece
plate). "0" on red dot (with eyepiece
plate), see Fig. 19.
Check that the eyepieces are inserted
into the tube to their stop.
3.
Set individual eye distance by shifting the
eyepiece tube laterally (Fig. 18/
2
), until only
one
complete light circle (specimen field) is
visible when looking into the eyepieces with
both eyes.
To this effect, a distance of approx.
2 cm must be maintained between the
eye and the eyepiece.
4.
Initially, set the zoom (Fig. 18/
3
) to the
smallest magnification.
5.
Focus on a small distinct detail in the center of
the specimen (Fig. 18/
4
).
6.
Adjust maximum zoom value (Fig. 18/
3
). Magnification will probably make the distinct detail appear
blurred and no longer in the image center.
7.
Sharpen the specimen by focusing, then shift the specimen to re-search for the detail and focus
"sharply" again (Fig. 18/
4
).
8.
Afterwards, reset to the lowest zoom value and correct any image blurring for each eye separately by
diopter compensation
on the adjustable eyepieces
(not on the focusing knob, Fig. 18/
4
)
(compensation of visual defect).
After adjustment of the stereo microscope, the image focus remains unchanged over the entire zoom
range.
After change of the observer, repeat steps
3.
to
8.
