Removing the attachable Pol object guide and mounting stage clips
•
Turn the control wheel (Fig. 3-16/
3
) of the Pol object guide (Fig. 3-16/
1
) until the clamping screw
becomes visible in the mounting hole (Fig. 3-16/
2
).
•
Use the Allen wrench to loosen the clamping screw. Remove the Pol object guide Pol upwards.
•
Insert the stage clips (Fig. 3-16/
4
) into the holes on the stage provided for this purpose.
•
Attach the Pol object guide (453560-0000-000) for the large rotary stage (453550-0000-000) in the
same way.
•
Attach the D Pol specimen holder for transmitted light specimens or the A Pol specimen holder for
reflected light specimens and mount the balance weight on the stage.
3.1.10.4
Removing the stage clips and attaching the Pol attachable object guide
•
Remove stage clips (Fig. 3-16/
4
) from rotary stage Pol.
•
Insert the Pol object guide (Fig. 3-16/
1
), introducing the two cylindrical pins on its underside into the
respective holes (Fig. 3-16/
6
) and tighten the clamping screw firmly (Fig. 3-16/
2
). Where required, turn
the control first to make the clamping screw accessible.
3.1.10.5
Centering the Pol rotary stage
With high-power objectives, stage centricity can be
exact only for one selected objective.
All stages are factory-pre-centered, i.e. when
rotating the stage the specimen feature set to the
center of the field of view will remain in the center.
If the specimen feature moves off the center of the
field of view (Fig. 3-17/
5
) while you are rotating
the stage, the stage should be re-centered as
follows.
•
Before centering the stage, you must adjust the
KÖHLER illumination on the microscope (see
section 4.2.1).
•
For stage centering, use a contrast-rich
specimen and an eyepiece with reticle.
•
Loosen the stage click-stop (Fig. 3-17/
4
) or
clamp (on the Pol rotary stage with clamping
device) and unscrew the stage carrier cap
(Fig. 3-17/
1
).
•
Rotate the stage to determine the position of maximum offset of the specimen feature (Fig. 3-17/
5
,
origin of arrow) from the center of the eyepiece reticle.
•
Turn the two centering screws on the stage carrier (Fig. 3-17/
2
) with one Allen wrench (AF 1.5)
3
) each to move the specimen feature by half the arrow length towards the reticle center.
Rotate the stage again to check if the specimen feature moves off. Repeat the centering procedure, if
necessary.
•
After centering, retighten the screw cap (Fig. 3-17/
1
).
