ADJUSTMENT & OPERATION
Adjusting the Interpupillary Distance
To adjust the interpupillary distance, hold the left and
right eyetubes while observing a specimen. Rotate
the eyetubes around the central axis until the fields of
view of both eyetubes coincide completely. A
complete circle should be seen in the viewing field
when viewing the specimen slide. An improper
adjustment will cause operator fatigue and will disrupt
the objective parfocality.
Where
“·”

on the eyepiece tube lines up, then that
is the number for the interpupillary distance.
Range
：
50
～
75mm. (Fig. 12).
Remember your interpupillary for future operation.
Adjusting the Focus
To ensure that you obtain sharp images with both
eyes (since eyes vary, especially for those wearing
glasses) any eyesight variation can be corrected in
the following manner: set both diopter collars to “0”.
Using your left eye only and the 10X objective, focus
your specimen by adjusting the coarse adjustment
knob
①
. When the image is in view, refine the image
to its sharpest focus by turning the fine adjustment
knob
②
. Rotate the diopter collar to obtain the
sharpest focus. To obtain the same sharp image
using your right eye, do not touch the coarse or fine
adjustments. Instead, rotate the right diopter collar
until the sharpest image appears. Repeat several
times to check.
NOTE:
do not counter rotate the focusing knob as
this will cause severe problems and damage to the
focusing system. (Fig. 13)
Adjusting the Focusing Tension
If the handle is very heavy when focusing or the
specimen leaves the focus plane after focusing or
the stage lowers by itself, please adjust the tension
adjustment ring
①
.
Located on the left side of the
stand between the coarse adjustment knob and the
vertical arm is an adjustable tension control dial
that is preset at our facility. This allows the user to
adjust the coarse control tension to their individual
preference. (Fig. 14).
