3.5 Converting the microscope
Unplug the plug-in power unit from
line power before converting the
microscope.
3.5.1 Changing the tube
•
Loosen the clamping screw (Fig. 26/ 2 ), turn the
installed tube (Fig. 26/ 1 ) clockwise by
approximately 90° (Fig. 26/ A ) and detach it on
the right side upward (Fig. 26/ B ).
For reasons of space, the tube may
also be clamped by the Allen set screw
supplied with the tube.
•
Insert the tube to be installed, with the
eyepieces pointing to the right and its dovetail
mount slightly inclined, under the two holding
elements (Fig. 26/
4 ) into the stand.
•
Then, place the tube horizontally onto the
stand. In doing so, the groove on the underside
of the tube must be located above the third
holding element (Fig. 26/
3 ) of the stand.
•
Turn the tube counterclockwise by 45°
(eyepieces pointing frontward), align it to the
stand and tighten the clamping screw
(Fig. 26/ 2 ).
For space-saving storage of the
microscope (e.g. in a cabinet) the tube
may also be rotated by 180° to the
back.
3.5.2 Inserting color filters
•
Move the condenser carrier fully up by turning
the knurled knob for vertical adjustment
(Fig. 16/ 22 ).
•
Unscrew the cover cap (Fig. 27/ 3 ) from the
luminous-field diaphragm (Fig. 27/ 1 ).
•
Put the desired filter – yellow, green or blue –
(Fig. 27/
2 ) onto the mounting surface of the
luminous-field diaphragm and screw the cover
cap back into place.
