Leica DM750 Manuel D’Utilisation

1.  Adjust the tubes to your interpupillary 

distance. Fold or unfold the eyetubes to 
decrease or increase the distance between 
the eyepieces until you see one illuminated 
circle.

 

The viewing tubes maintain a constant 
tube length for all interpupillary settings. 

This means that a change of interpupillary 
distance does not affect parfocality, magnifica-
tion, or calibrations that depend on magnifica-
tion. 

 

Ϙ

If you are using a Leica EZ viewing tube, 
which has the eyepieces integrated with 
the eyetubes, no additional adjustments 
are necessary. Be sure you are wearing your 
eyeglasses or contact lenses.

 

Ϙ

If you have a Leica DM750 with stan-
dard illumination (without Koehler field 
diaphragm), continue with the "Oil Immer-
sion Technique" section on page 40.

If you have a Leica DM750 with Koehler 
field diaphragm, continue with the "Koeh-
ler Configuration" section on page 38.

 

Ϙ

If you are using a standard viewing tube 
with two fixed eyepieces (no focusing 
eyepieces), no additional adjustments 
necessary. Be sure you are wearing your 
eyeglasses or contact lenses.
