Leica DM100 User Manual 27
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.
Leica EZ tubes
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.
Open Binocular Tube
If you are using an open standard tube, you
need to make some adjustments.
1. Set the focusing eyetube (left side) to "0"
