10.4 Adjust the observation head

Loosen the locking screw ①, turn the observation head to a com-
fortable position for observation, and then lock the locking screw
again. (Fig. 21)

10.5 Adjust the interpupillary distance

Observing with both eyes, hold the two eyepiece prism assem-
blies. Rotate them around their common axis until the fields of
view match.
• The graduation on the interpupillary distance indicator
②, pointed by the spot "." on the eyepiece holder, shows
the distance between the operator's eyes. (Fig. 22)
The range of the interpupillary distance is 48-75 mm.

10.6 Diopter adjustment

1. Look into the right eyepiece with your right eye only, and
focus on the specimen.
2. Look into the left eyepiece with your left eye only. If the
image is not sharp, use the diopter adjustment ring ③ to
compensate. (Fig. 23)
• The adjustment range is ±5 diopter. The number indicated
on the adjustment ring graduation should correspond to
the operator's diopter correction.

10.7 Use of eyeshields

• Use with eyeglasses
Fold rubber eyeshields with both hands. Folded eyeshields avoid
scratching the lenses of eyeglasses. (Fig. 24)
