Diopter Adjustment; Interpupillary Distance Adjustment - Nikon Eclipse LV100POL Instructions Manual

Diopter Adjustment

Diopter adjustment compensates for
differences in visual acuity between the right
and left eyes. This adjustment improves
binocular observation and minimizes focal
deviation when switching objectives.
In the case of a polarization microscope, since
an eyepiece containing crosshairs is used for
the right eye, the procedure for adjusting the
diopter differs from that of an ordinary
microscope.
1 Observe the right eyepiece with the
right eye. Turn the diopter adjustment
ring to bring the crosshair in the
eyepiece into focus.
2 Still observe the right eyepiece with the
right eye. Turn the fine/coarse focus
adjustment knob to bring the specimen
on the stage into focus.
3 Observe the left eyepiece with the left
eye. Turn the diopter adjustment ring on
the eyepiece to bring the specimen into
focus. (not the fine/coarse focus
adjustment knob)

Interpupillary Distance Adjustment

Interpupillary distance adjustment improves the
ease of binocular observation.
Perform steps 1 to 14 on Page 12 "Diascopic
Bright-Field Microscopy" and focus on the
specimen using the 10x objective. Then, move the
eyepiece sleeve until the view fields for the right
and left eyes coincide.
In addition, the binocular part has a scale for the
interpupillary distance. Make a memo of your
interpupillary distance for future adjustments.
