ADJUSTMENT  
AND OPERATION 

Adjusting Binocular Viewing Head 

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

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

to the highest 

magnification 3x, then turn the focusing knob

to focus the specimen.

Rotate the zoom knob

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

can be mounted onto 

higher or lower positions according to your 
needs by removing the clamping bolt with the 
Allen wrench provided.
