8.5 Focusing

Leica DMI3000 B and Leica DMI4000 B:

The left-hand focus wheels can be used for both coarse and fine focusing; the right-hand focus wheel for fine focusing only (a version of the Leica DMI3000B 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. 98) 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 LeicaScreen. In the case of motorized stages, the Z drive will travel to its lowest position prior to the stage initialization when switching the mi- croscope on.

The focus buttons Z″ and Z on the right side of the stand (Fig. 114) permit fast focusing or low- ering of the objectives.
