8.5 Focusing
Leica DMI3000 B and Leica DMI4000 B:
The left-hand focus wheels can be used for both
coarse and fi ne focusing; the right-hand focus
wheel for fi ne focusing only (a version of the
Leica DMI3000 B with mirrored focus controls is
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,
p. 101) on the SmartMove remote control module.
Alternatively, use the focus wheels on either side
of the stand.
The current Z position is shown on the LeicaS-
creen. In the case of motorized stages, the Z
drive will travel to its lowest position prior to the
stage initialization when switching the micro-
scope on.
