Centering the stage
When objectives with high magnification are used,
centering can be exact for one selected objective
only.
All stages are factory-precentered, i.e. a set
specimen detail remains in the image center when
the stage is rotated. If the image detail moves from
the image center (3-53/
4
), while you rotate the
stage, recenter the stage as follows:
•
Loosen stage clamping screw (3-53/
1
) and the
screw cap on the stage carrier (3-53/
3
).
•
Rotate the stage to determine the maximum
specimen deflection (3-53/
4
, tip of arrow) to
the eyepiece reticle.
•
Reset the two centering screws on the stage
carrier (3-53/
2
) using one SW 1.5 Allen screw-
5
) each to move the specimen
detail by half the arrow length in the direction
of the crossline center. Check whether the
specimen detail moves when the stage is
rotated again; repeat the procedure, when
required.
•
When centering is finished, tighten screw cap
(3-53/
3
) again.
The stage can be turned through 240° up to a motion range of y
≤
27 mm. No rotation is possible above
this range of movement.

Adjusting the travel range on ergonomic drive
On mechanical stages with ergo-drive, the length of the
x
and
y
stage drive can be extended by
max.
15 mm
by axial movement of the drive knobs to further improve operating ease.
