5. Dioptric adjustment (Fig. 9)
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
dioptric adjustment ring ① to compensate.
(Fig.9)
► The adjustment range is ±5 diopter. The
number indicated on the adjustment
ring graduation should correspond to
the operator's dioptric correction.
6. Adjusting the interpupillary distance
(Fig. 10)
Observing with both eyes, hold the two eye-
piece prism assemblies. Rotate them around
their common axis until the fields of view co-
incide.
► 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.10)
The range of the interpupillary distance is 48-
75mm.
