Adjust the diopter.
(See Chapter 2, Section 4 in the instruction manual for details)
(1)
Turn the diopter adjustment ring on the right and
left eyepieces to align the end face of the diopter
adjustment ring with the line.
(This is the diopter adjustment reference position.)
(2)
Focus on the specimen using the 40x objective.
(3)
Bring the 10x (or 4x) objective into the optical path.
(4)
Look into the right eyepiece with your right eye and the left
eyepiece with your left eye. Turn the diopter adjustment ring
of each eyepiece to focus on the specimen.
At this point no focus knobs are used.
(5) Repeat steps (2) through (4) to make sure the focus has been
adjusted properly.
8
Adjust the interpupillary distance.
Look into both eyepieces and rotate the binocular part to adjust
the binocular part's opening until the fields of view for the right
and left eyes coincide.
9
Focus and center the condenser.
(See Chapter 2, Section 5 in the instruction manual for details)
(1) Look into the eyepiece with the field diaphragm stopped down
to the minimum. Focus on the field diaphragm image using
the condenser focus knob, then adjust the condenser centering
screws to center the diaphragm image within the field of view.

(2)
Bring the 40x objective into the optical path to check the focus
and centering of the field diaphragm image. Make adjustments
in the same way as step (1) as necessary.
(3)
Turn the field diaphragm dial and adjust the field diaphragm image
so that its size is almost the same as the field of view.
10
Select the desired objective.
Turn the nosepiece to bring the desired objective into the optical path.
For easy adjustment, look into
the eyepiece as if you were looking
at a distant object.

Field of view
Opening the field diaphragm too much
results in stray light entering the field
of view, generating flare and reducing
the image contrast.
Be sure to adjust the field diaphragm
each time you change the objective.
