Adjusting the Field Diaphragm
-
Reflected Illumination
By limiting the amount of light entering the
condenser, the field diaphragm can prevent
other light and strengthen the image contrast.
When the image is just on the edge of the field
of view, the objective will obtain the clearest
image.
Push the field diaphragm adjustment lever  all
the way in to minimize the field diaphragm.
Observe the image through the eyepiece and
adjust the field diaphragm centering lever  until
the image is in the center.
Slowly open the field diaphragm adjustment
lever . When the image in the diaphragm field
in aligned with the field of view, the field
diaphragm is centered.
