To correct defective eyesight:
● Look through the right-hand eyepiece tube
with your right eye and sharply focus the
specimen with the fine drive.
● Then look at the same area of the specimen
with your left eye and rotate the left eyepiece
tube until you obtain a sharp image. Do not
use the fine drive for this.
● If using eyepieces with adjustable eyelenses,
do not compensate for defective eyesight by
adjusting the eyepiece tube, but by adjusting
the eyelens of the eyepiece.
Trinocular tube HCI 3T22
● Set the beamsplitter at visual observation by
pushing in the switch rod. The switching
positions are indicated by symbols on the
side of the tube.

● The eyepieces are set in exactly the same
way as on the binocular tube.
● Compensate defective eyesight by adjusting
the eyelens of the eyepiece.
