3.1.7.4
Removing the stage clips and mounting the detachable Pol specimen guide
•
Remove the stage clips (Fig. 3-10/
9
) from the Pol rotary stage.
•
Insert the Pol specimen guide (Fig. 3-10/
2
) with the two cylindrical pins on the underside into the holes
provided (Fig. 3-10/
3
) and tighten the two clamp screws (Fig. 3-10/
1
) with an Allen wrench (AF 2).
3.1.7.5
Centering the Pol rotary stage
With high-power objectives, centering can be exact
only for one selected objective.
All stages are factory-precentered, i.e. while
rotating the stage the specimen feature set to the
center will remain in the center. If the specimen
feature moves out of the center of the field of view
(Fig. 3-11/
5
) while the stage is being rotated, the
stage should be re-centered by following this
procedure:
•
The KÖHLER illumination on the microscope
must be adjusted before centering the stage
(see section 4.2.1).
•
Turn the nosepiece to swing the non-centering
objective mount.
•
For centering the stage, use a contrasting
specimen and an eyepiece with a crossline
reticle.
•
Loosen the stage clamping screw (Fig. 3-11/
1
) and the screw cap on the stage carrier (Fig. 3-11/
3
).
•
Rotate the stage to determine the position of maximum offset of the specimen feature (Fig. 3-11/
5
,
origin of arrow) from the center of the eyepiece reticle.
•
Reset the two centering screws on the stage carrier (Fig. 3-11/
2
) using an Allen wrench (AF 1.5)
4
) to move the specimen detail by half an arrow length in the direction of the crossline
center. Check whether the specimen detail moves when the stage is rotated again; repeat the
procedure, if required.
NOTE
The Allen wrenches (AF 1.5) are located in the storage compartment at the back of the
microscope stand.
•
When centering is finished, re-tighten the screw cap (Fig. 3-11/
3
).
