USING AND ADJUSTING YOUR MICROSCOPE
Viewing Head:
The viewing head is inclined 30 degrees to enable comfortable observation and ro-
tates 360 degrees to permit observation from any direction. To rotate it, loosen the
head locking thumb screw and tighten it when the head is located at the position you
desire. Do not use the microscope without tightening the thumb screw. The optical
alignment is adjusted to be used with the thumb screw tightened.
The binocular and trinocular head, require interpupillary adjustment. To adjust the
eyepieces to the interpupillary distance between your eyes, please grasp the right &
left housings below the eyepiece tubes and move them farther apart or closer to-
gether in order to match your pupil distance. The correct adjustment is achieved
when your view becomes comfortable and presents a full single field. Read the in-
terpupillary scale and remember the distance of your pupil for your future use.
The dioptric adjustment ring is located on the left eyepiece tube. To correct a diop-
tric difference between your eyes, begin by looking through the right eyepiece with
your right eye, use the fine focusing handle to get the sharpest image of the speci-
men. Then, look through the left eyepiece with your left eye and turn the dioptric
adjustment ring until you get an image in the same sharpness as the right one. Make
the left eye adjustment without moving the focusing handle.
The CN series has Siedentopf type binocular or trinocular head is designed
to leave the mechanical tube length of 160mm unchanged when the interpupillary
distance is adjusted. This will not affect the diopter adjustment.

the other hand. Do not carry or hold the microscope any other way.
