OPERATION

(continued)

Adjusting the Field Diaphragm

(Fig. 18-19)

By limiting the diameter of the light entering the
condenser, the field diaphragm can prevent stray light
and improve the image contrast. When the image is just
on the edge of the field of view, the objective can show
the best performance and obtain the clearest image.

Move the field diaphragm lever (FS)

①

in or out to

adjust the field diaphragm.

The image of the field diaphragm can be seen when
observing through the eyepiece.

The field diaphragm was pre-centered prior to shipment.
If the field diaphragm needs to be adjusted, adjust the
right and left centering
screws

②

using the hex screwdriver until the field

diaphragm is centered in the field of view.

Using the Aperture Diaphragm

(Fig. 20-21)

The iris diaphragm determines the numerical aperture
(N.A.) of the illumination system in bright field
observation. When the N.A. of the objective and the
illumination system match, you can obtain higher image
resolution and contrast, as well as an increased depth of
focus.

Move the aperture diaphragm lever (AS)

①

in or out to

adjust the aperture diaphragm so that the aperture
diaphragm image covers 70% to 80% of the pupil of the
objective.

To properly adjust the aperture diaphragm adjust the
right and left centering screws

②

using the hex

screwdriver until the aperture diaphragm is centered in
the field of view.
