Adjusting the Interpupillary Distance
# Be sure to hold the binocular assembly @ with both hands to make
this adjustment.
To prevent damaging the mechanism, do not apply an excessive
force beyond the stop position.
While looking through the eyepieces, hold the left and right of the binocular
assembly @ and adjust the eyepieces by opening or closing them for
binocular vision until the left and right fields of view coincide completely.
Adjusting the Diopter
2
(Zoom Parfocal Adjustment)
}Ensure that the eyepiece clamping knob @ is tightened before starting
the adjustment.
Adjusting the diopter specific to the two eyes of each observer allows the
parfocality to be ensured across zoom magnifications.
When Not Using the Eyepiece Micrometer Disk
1. Look into the right eyepiece and rotate its diopter adjustment ring ² so
that the peripheral part of the visual field looks sharply.
2. Place an easy-to-observe specimen on the stage plate.
3. Rotate the zooming knob ³ to a low magnification and, looking only into
the right eyepiece, focus the specimen using the coarse and fine focus
adjustment knobs.
4. Rotate the zooming knob ³ to the highest magnification and, looking
only into the right eyepiece, focus the specimen using the coarse and
fine focus adjustment knobs.
5. Rotate the zooming knob ³ to the lowest magnification, look only into
the left eyepiece, and focus the specimen by rotating the left diopter
adjustment ring | instead of the coarse and fine focus adjustment knobs.
When Using the Eyepiece Micrometer Disk
1. Look into the right eyepiece that includes the eyepiece micrometer disk,
and focus the micrometer disk by rotating the diopter adjustment ring ².
2. Place an easy-to-observe specimen on the stage plate.
3. Rotate the zooming knob ³ to the highest magnification and, looking
only into the right eyepiece, focus the specimen using the coarse and
fine focus adjustment knobs.
Ensure that both the eyepiece micrometer disk and specimen are focused
accurately.
4. Rotate the zooming knob ³ to the lowest magnification, , look only into
the left eyepiece, and focus the specimen by rotating the left diopter
adjustment ring | instead of the coarse and fine focus adjustment knobs.
}Note (or memorize) the diopter readings of the left and right eyepiece
scales so that they can be duplicated quickly in the next observation.
