Operation of the Binocular Observation Tube with Photo Tube
1. Select the Light Path.

Operation of the light paZh selector knob
located on the righz side
of
the tube deflects
the light in three directions as explained in the

Diopter Correction
Dilferences in eye acuily are often present in the
same
person
so
that long
time
microscopic observation would put: considerable strain on the observer's eyes. There-
fore, cliopter adjustment of both eyes is a very useful aid.
Color on
Knob Shaft
(Indicator Plate)
To adjust
for your correct diopter setting: (Fig. 1
8)
1) Look through the rlght eyepiece with your
right eye and focus on the specimen.

2) Next,
look
through the left eyepiece with
your left eye
and turn the diopter adjustment
ring on the eyepiece tube to focus on the
speci men.

I nterpupillary Adjustment
Because of the constant tube length adjustment
built into the observation tube, the mechanical
YI

tube length does not change
a t
all i f the inter-
pupillary distance of the eyepiece tubes is varied.
Hold the right and
left
eyepiece tubes with both
hands and push the tubes together, or pull them
...
apart, whichever is required, while looking through
the eyepieces with
both eyes, until perfect
binocular vision is obtained, (Fig. 19)
I t
is good
practice to memorize the individual
interpupillary distance setting.
A scale is provided for this purpose, located
. .
between the eyepiece tubes.
