The objective nosepiece is lowered to the lower thres-
hold. This makes it possible to apply the immersion fluid
when switching from the dry objective to the immersion
objective. Conversely, the immersion fluid can be re-

The current objective remains in the beam path.

is now approached.
Note:
For lockable immersion objectives, press the front part
upwards as far as it will go (approx. 2 mm). Then, after a
gentle turning motion to the right, the objective is locked.
For objectives with a correction mount, adapt the objec-
tive to the thickness of the cover slip by turning the knurled
knob.
Note:
If objectives are retrofitted, they have to be taught in using
the LAS X software: Afterwards, the parfocality should also
be taught in again.
See the instructions for the LAS X.
