Leica DM100 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. 

If you are using a Leica EZ viewing tube, which 
already has the eyepieces integrated with the 
eyetubes, no additional adjustments are neces-
sary. Be sure you are wearing your eyeglasses or 
contact lenses. Continue with the "Oil immer-
sion" section on page 30.

If you are using an open standard tube, you 
need to make some adjustments.

1.  Set the focusing eyetube (left side) to "0"
