3. Adjustment of phase-contrast device
Set the phase contrast puller
①
to the central light hole, as shown in Fig.7.
4. Reset of diopter adjustment ring
Turn the d
iopter adjustment
ring
①
on the left eyepiece tube, so that the
“
0
”
d
iopter
position is
aligned with the side scale (remark white line), as shown in Fig.8.
5. Adjustment of interpupillary distance
Parallax can be eliminated by adjusting the interpupillary distance so that the distance of the
eyepiece tube is identical with your interpupillary distance and enable you to observe more
comfortably and clearly. When you observe through two eyepieces, if the field of view consists of
two overlapping circles, as shown Fig.8-a, you can alter the exit pupil center distance of the
eyepiece tubes by turning the left or right frame body
②
until the field of view becomes a fully
overlapped circle, as shown in Fig. 8-b.
6. Inspection of transmitted lighting path
The optical system of this unit has been calibrated before factory release. But the center of the
lighting bulb or condenser system may deviate from the center of the optical system due to any
possible violent vibration or inclination during transport. After the above installation and
adjustment, the light path of the optical system should be checked.
(1) Inspection of center of field diaphragm
A. Put the test slide
①
.as an example in the selected Stage bracket
②
. Turn the 10X plan
objective
③
into the light path. Turn the stage moving device control knob and
④
and
⑤
to move the slide right above the 10X objective. Adjust the focus by the coarse and fine focus
knobs
⑥
and
⑦
to make the image of slide in the field of view clear. As shown Fig.9.
