(Immersion)
Each objective belongs to one of the following
categories:
1) Dry objectives (DRY)
2) Immersion objectives (IMM)
Note:
It is possible to assign one objective to both
operation modes, especially with dry objectives
with >2mm working distance. The setting can be
changed with Software Leica DMControl,
module: Fine Tuning.
Changing the operation mode
• First select the operation mode (IMM or DRY)
on the LeicaScreen, navigation item
.
The operation mode can also be selected with
the Software Leica DMControl.
• The stage is lowered by 3mm. This enables
you to apply the immersion oil when changing
from dry to immersion objectives. In the
reverse case, the oil can be removed.
The current objective remains in the beam
path.
• Now press the button for the objective you
want to select. You can also press the gray
button for the currently activated objective.
The objective will be rotated into the beam
path.
• Start with a small level of magnification. Then
switch to the next higher objective.
• For
immersion objectives

immersion medium.
