Adjusting Interpupillary Distance (Fig.6)
Different users have different interpupillary
distances (this distance is between the centers
of pupils of each eye). When operators of the
microscope change, it will be necessary to
adjust interpupillary distance.
While looking through the eyepieces, hold the
left and right eyepiece tubes of the binocular
assembly ① and adjust the eyepiece tubes by
opening or closing them until the left and right
fields of view coincide completely and you are
able to see a complete circle.
Adjusting Diopter Ring (Fig.7)
Set the diopter rings of both eyepieces to "0"
(zero) position. (Do this when users change,
because different users will have different
diopter settings.)
Place an easy-to-observe specimen on the
stage plate, i.e., a coin.
Rotate the zoom knob ③ to the highest
magnification 3x, then turn the focusing knob ④
to focus the specimen.
Rotate the zoom knob ③ to the lowest
magnification 0.7x, looking only into the left
eyepiece, adjust the diopter ring on left eyepiece
to focus the specimen. Then repeat procedure
for the right eyepiece.
NOTE: The working distance of the microscope
is 97mm (the distance between the microscope
objective to the top of the specimen), the
binocular head bracket ⑤ can be mounted onto
higher or lower positions according to your
needs by removing the clamping bolt with the
Allen wrench provided.
