Leica DM IRB manual Focus

FOCUS

Here the arrow keys control the movement of the Z drive.

The movement speed for the fine focusing is selected with the STEP key. For safety reasons, the movement range is limited to 400 μm above the focus position and 400 μm below the lower Z position.

If both arrow keys are pressed at the same time, the system switches to coarse focusing (SC). The Z drive then moves at a higher speed. Here, the movement range is limited by the set threshold (lower Z position) and at the top end by the focal plane (focus position), to prevent collision damage. The coarse focus is switched off the moment the two arrow keys are pressed simultaneously again or a specific focus speed is selected with the STEP key.

The AF key is not assigned yet.

X-Y

The arrow keys define the direction in which the stage is to move.

Two different speed modes can be preselected (Slowmode/Fastmode) with the SPEED key. The travel speed is increased as a function of the speed mode with a predefined ramp: the longer one of the arrow keys is pressed, the faster the stage moves. The speed mode determines the maximum speed.

FOOT

The left footswitch is assigned a function via key 1, the right footswitch via key 2.

After the microscope is switched on, the foot- switches have the default function Magnifi- cation change.

To assign a different function, first press key 1 or 2 and then the desired function key. An acoustic signal is given for correct inputs.
