Dioptric adjustment
1. Put the scale of each eyepiece on the "0"
position. (Fig 17).
2. Using focusing knobs, focus the specimen
with the right eye.
3. Look into the left eyepiece with your left
eye only. If the image is not sharp, use the
dioptric adjustment ring ① to compensate.
► The adjustment range is ±5 diopter. The
number indicated on the adjustment
ring graduation should correspond to
the operator's dioptric correction.
Adjusting the interpupillary distance
Observing with both eyes, hold the two
eyepiece prism assemblies. Rotate them
around their common axis until the fields of
view coincide.
► 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. 18)
The range of the interpupillary distance is 48-
75mm.
