Adjusting the Interpupillar Distance
# Be sure to hold the binocular assembly @ with both hands to
make this adjustment.
While looking through the eyepieces, hold the left and right of the bin-
ocular assembly @ and adjust by opening or closing it for binocular
vision until the left and right fields of view coincide completely.
Adjusting the Diopter
3
(Zoom Parfocality Adjustment)
}Make sure that the eyepiece clamping knobs @ are tightened. Adjust-
ment of the diopter according to the user's eyesight ensures parfocality
even when the zoom magnification is changed.
1. Looking into the right eyepiece, rotate the diopter adjustment ring ² so
that the outer periphery of the field of view is as sharp as possible.
2. Place an easy-to-observe specimen on the stage.
3. Rotate the zooming knob ³ to a low zoom ratio and focus the specimen
using the coarse and fine focus adjustment knobs.
4. Rotate the zooming knob ³ to the highest zoom ratio and focus the
specimen using the coarse and fine focus adjustment knobs.
5. Rotate the zooming knob ³ to the lowest zoom ratio, then focus the
specimen by rotating the left and right diopter adjustment rings |
instead of the coarse and fine focus adjustment knobs.
When Using the Micrometer Eyepiece
1. Look into the micrometer eyepiece and focus on the micrometer scale
by rotating the diopter adjustment rings ².
2. Place an easy-to-observe specimen on the stage.
3. Rotate the zooming knob ³ to a low zoom ratio and focus on the
specimen looking into the micrometer eyepiece and using the coarse
and fine focus adjustment knobs.
4. Rotate the zooming knob ³ to the highest zoom ratio and focus on the
specimen using the coarse and fine focus adjustment knobs.
5. Rotate the zooming knob ³ to the lowest zoom ratio, then focus the
specimen by rotating only the diopter adjustment ring | of the non-
micrometer eyepiece 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.
