3.1.8.4 Removing the stage clips and mounting the detachable specimen guide Pol

x Remove the stage clips (Fig. 3-12/9) from the rotary stage Pol.

x Insert the specimen guide Pol (Fig. 3-12/2) with the two cylindrical pins on the underside into the holes

provided (Fig. 3-12/3) and tighten the clamp screw (Fig. 3-12/1).

3.1.8.5 Centering rotary stage Pol

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 off the center of the field of view

(Fig. 3-13/5), while rotating the stage, the stage

should be re-centered by following this procedure:

x The KÖHLER illumination on the microscope

must be adjusted before centering the stage

(see Section 4.1.1).

x Turn the nosepiece to swing the non-centring

objective mount.

x For centering the stage, use a contrasting

specimen and an eyepiece with crossline reticle.

x Loosen the stage clamping screw (Fig. 3-13/1)

and screw cap on the stage carrier (Fig. 3-13/3).

x Rotate the stage to determine the position of

maximum offset of the specimen feature

(Fig. 3-13/5, origin of arrow) from the center of

the eyepiece reticle.

x Reset the two centering screws on the stage carrier (Fig. 3-13/2) using a SW 1.5 socket wrench

(Fig. 3-13/4) 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, when required.

The SW

1.5 socket wrenches are located in the storage compartment on the rear side of the

microscope stand.

x When centering is finished, re-tighten screw cap (Fig. 3-13/3).
