Precise Centering of the Mirror
}The position of the mirror has been adjusted and locked before ship-
...
ment. Only if you want more precise adjustment of the mirror position,
proceed to the following steps immediately after the procedure in the
previous paragraphs.
Note that, once the following steps are completed, it is no longer pos-
sible to restore the mirror position in the factory shipped condition.
†
1. Using a pair of tweezers, etc., peel off the two blind stickers † on the rear
of the lamp housing.
2. Fit the Allen screwdriver into each of the screws hidden below the stick-
ers and loosen them. Loosening the two screws releases the locking of
the mirror.
3. Peel off other two blind stickers ‡ to expose the mirror centering holes.
4. Insert the Allen screwdriver into the screw in each mirror centering hole
and adjust the centering of the mirror-reflected image.

Centering the Field Iris Diaphragm
1. Set the shutter knob to "{" to close the light path with the shutter.
2. Rotate the mirror unit turret to engage a mirror unit in the light path.
3. Set the shutter knob to "¦" to open the shutter.
4. Place a specimen on the center of the base and bring the specimen into
approximate focus.
5. Pull out the field iris diaphragm lever @ on the illuminator to stop down
the field iris diameter near the minimum size.
6. Insert the Allen screwdriver, provided with the microscope body, into the
two field iris diaphragm centering screw ² and adjust so that the field iris
image comes on the center of the field.
7. Push in the field iris diaphragm lever @ until the field iris image inscribes
the field of view. If the field iris image is found to be eccentric, adjust
centering again.
8. Open the iris until the field iris image size becomes equivalent to the field
size (i.e. until the field iris image circumscribes the field of view).
