8.5 Focusing

Leica DMI3000 B and Leica DMI4000 B:
The left-hand focus wheels can be used for both

wheel for fine focusing only (a version of the

also available)
Leica DMI6000 B:
Note:
The parfocality teach-in has already been per-
formed at the factory. However, it may be neces-
sary to perform another teach-in after installing
the objectives when setting the microscope up.
We recommend checking parfocality before set-
ting the stops and performing a teach-in with the
Leica Application Suite (LAS) if necessary.
Focusing the image
The focusing is controlled by the knobs (116.3,
