b) How to mount the stage
•
Loosen the screw caps (
338H
Fig. 3-12/
2
) of the spring box with approx. 3 turns.
•
Put the stage with the dovetail ring notch onto the spring pin (
339H
Fig. 3-12/
1
).
•
Press the stage forward against the spring pin and lower its back side into the stage carrier
(
340H
Fig. 3-12/ 3 ).
•
Tighten the screw caps (
341H
Fig. 3-12/ 2 ).
c) How to center the stage
When using objectives with a high magnification,
only one selected objective can be centered exactly
at a time.
All stages are delivered pre-centered, i.e. when the
stage is turned, the detail of the specimen in the
focus remains in the center of the image. If the
detail shifts out of the center when the stage is
turned (
342H
Fig. 3-13/ 5 ), then it becomes necessary to
re-center the stage.
•
Loosen the clamping screws of the stage
(
343H
Fig. 3-13/
4
) and the screw cap of the stage
carriers (
344H
Fig. 3-13/
1
).
•
Determine the maximal shift of the specimen
(
345H
Fig. 3-13/ 5 , arrow point) to the cross line in the
eyepiece by turning the stage.
•
Shift the specimen detail towards the center of
the cross line by turning each the two centering
screws on the stage carrier (
346H
Fig. 3-13/ 2 ) with an
Allen wrench (AF 1.5) (
347H
Fig. 3-13/ 3 ) half the
length of the arrow. Repeat the procedure if
the specimen detail shifts out of the center
again when turning the stage.
•
After finishing the centering procedure tighten the screw caps (
348H
Fig. 3-13/ 1 ) again.
The stage can be turned by 240° within a shifting range of y
≤
27 mm. No turning of the stage is possible
outside of this range.
(3) Adjusting the drive length on the ergonomic drives
An axial shift of the coaxial knurled knobs by a maximum of 15 mm can extend the drive length of the
X
and
Y
shift on the mechanical stages with ergonomic drives.
