Leica DM IRB manual Motorized objective nosepiece

Motorized objective nosepiece

The electronic nosepiece control allows easy and safe change of the objective magnification. Objectives are changed with 2 push buttons (objective changing keys) which are easily accessed behind the focusing handwheel on the left of the microscope.

Left side of microscope

The upper key is pressed to increase the magnification, the lower key to decrease the magnification. Short pressure on the key switches to the next lower or higher magnification. If you sustain the key for longer then 0.3 sec., the display jumps to the next higher or lower magnification every 0.5 sec. The nosepiece is not actually turned until you choose a specific magnification by releasing the key. All you have to do to switch from any higher magnification down to survey magnification, for example, is to sustain the lower objective key for approx. 3 sec. The selected objective is turned into the light path in the direction that involves the shortest travel distance.

n. b.:

When installing the system (see “Individual user adjustments”, → p. 48) it is possible to operate the objective change function on the right side of the microscope instead of the left.
