Leica M165 C B Manuel D’Utilisation

1. Set the dioptric correction for both 

eyepieces to "0".

2.  Select the lowest magnification and focus 

on a flat specimen.

3.  Select the highest magnification and read-

just the sharpness.

4.  Select the lowest magnification again, but 

do not look into the eyepieces. 

6.  Rotate the eyepieces counterclockwise in 

the "+" direction as far as they will go (+5 
diopter settings).

Leica stereomicroscopes are parfocally 
matched. The prerequisite for this is the correct 
setting of the diopters and the parfocality. The 
following adjustments have to be carried out 
only once by each user.

 

★

Move the lever of the video/phototube to 
the "observation" position and open the 
diaphragm.

7.  Look into the eyepieces.

8.  Slowly rotate each eyepiece individually 

in the "–" direction until each eye sees the 
object sharply imaged. 

9.  Select the highest magnification and refo-

cus if necessary.

Now, if you adjust the magnification from the 
lowest to the highest level, the specimen is 
always brought into sharp focus. If not, repeat 
the process.
