Centering the Field Iris Diaphragm (FS)
}Since the field iris diaphragm is usually used in the fully open condition,
the illuminator employs a method in which the auxiliary lever 4 is inserted
as required.
1. Press the BF button 1 of the hand switch to select the reflected light
brightfield light path.
2. Press the objective button 3 of the hand switch to engage the 10X
objective in the light path, place the specimen on the specimen table
and bring the specimen into approximate focus.
3. Screw the field iris diaphragm auxiliary lever 4 into the illuminator and
pull the lever to stop down the field iris diaphragm.
4. Insert the Allen screwdriver, provided with the illuminator, into each of the
two FS centering screws 5 and turn them until the field iris diaphragm
image becomes concentric with the field iris.
5. While pushing in the field iris diaphragm auxiliary lever 4, open the field
iris diaphragm until the field iris diaphragm image is inscribed with the
field of view. If their centers are deviated, center the field iris diaphragm
again.
6. Open the field iris diaphragm until the field iris diaphragm image circum-
scribes (becomes the same size as) the field of view.
