ADJUSTMENT
AND OPERATION
Adjusting Trinocular Viewing Head
Adjusting Interpupillary Distance (Fig. 6)
Different users have different interpupillary distances
(this distance is between the centers of the pupils of
each eye). When the operator changes, it will be
necessary to adjust the interpupillary distance.
While looking through the eyepieces, hold the left
and right eyetubes of the viewing head
and adjust the
eyetubes by opening or closing them until the left and
right fields of view coincide completely and you are
able to see a complete circle.
Adjusting Diopter Ring (Fig. 7)
Set the dioptor rings
②
of both eyepieces to “0”
position. (Do this when users change, because
different users will have different diopter settings.)
Place an easy-to-observe specimen on the stage
plate, i.e., a coin.
Rotate the zoom knob
③
to the highest
magnification 5x, then turn the focusing knob
④
to
focus the specimen.
Rotate the zoom knob
③
to the lowest magnification
0.8x, looking only into the left eyepiece, adjust the
diopter ring on left eyepiece to focus the specimen.
Then repeat procedure for the right eyepiece.
NOTE:
The working distance (the distance between
the microscope objective to the top of the specimen)
of the microscope is 115mm, the trinocular head
bracket/focus mount
⑤
can be mounted onto higher
or lower positions according to your needs by
removing the clamping bolt
②
(Fig. 9 next page)
with the Allen wrench provided.
Third Optical Path Parfocality Adjustment (Fig. 8)
After adjusting the diopter, the image should be
clear both in the eyepiece and the camera. If the
image is not clear in the camera, remove the rubber
screw cover
⑥
, loosen the inner screw and rotate
the screw with a flat head screwdriver until the
image is clear. When clear, tighten the screw and
replace the screw cover.
