• Press stage to the front against spring pin and lower its back in the stage carrier (2-35/3), then let go.
• Tighten screwing cap (2-35/2).
c) Centering the stage
When objectives with a 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 even
when the stage is rotated. If the image detail moves
from the image center (2-36/5) after stage rotation,
recentering should be performed as follows:
• Loosen stage clamping screw (2-36/4) and
screwing cap of the stage carrier (2-36/1).
• Rotate the stage to determine the maximum
specimen deflection (2-36/5, tip of the arrow) in
the direction of the eyepiece reticle.
• Reset the two centering screws on the stage
carrier (2-36/2) using one SW 1.5 Allen
screwdriver (2-36/3) each to move the specimen
detail by half the arrow length in the direction of
the crossline center. Check whether specimen
detail moves when the stage is rotated again;
repeat the procedure, if required.
• When centering is finished, tighten screwing cap (2-36/1) again.
The stage can be turned 240° up to a range of y ≤ 27 mm. No rotation is possible above this range of
movement.
