The objective turret of the DMI4000 B is coded
so that the selected objective is shown on the

When selecting an objective, the microscope au-
tomatically selects:
• the optimal setting for the fi eld diaphragm
• the optimal setting for the aperture diaphragm
• the light intensity for the current contrast
method
The objective magnifi cation and total magnifi ca-
tion are displayed on the LeicaScreen.
Note:
We recommend running a teach-in via the Leica
Application Suite (LAS) software when using
eyepieces not included in the scope of deliv-
ery. This will ensure that the total magnifi cation
shown in the LeicaScreen is correct.
