8.12 Aperture and Field Diaphragm

Leica DMI3000 B:

¥The manual aperture diaphragm is adjusted on the condenser.

¥The manual field diaphragm is adjusted on the illumination arm.

Leica DMI4000 B and Leica DMI6000 B:

Both diaphragms have been set to suitable val- ues for the current objective and contrast method at the factory.

The aperture diaphragm is controlled manually when using the manual condenser.

The field diaphragm is controlled manually when using the manual illumination arm.

¥The motorized diaphragms can be adjusted at any time with the AP (aperture diaphragm) (118.1) and FD (field diaphragm) (118.3) func- tion buttons. The values displayed on the LeicaScreen change accordingly.

The function buttons are assigned to the cur- rently active transmitted light (TL) or incident light (IL) axis.

Caution:

The old values will be overwritten by the current ones!

Caution:

When using PH or DF, the aperture diaphragm is fully open and can not be closed.
