When replacing objectives, you must perform a
teach-in for the new objectives in the Leica Ap-
plication Suite (LAS). A parfocality teach-in
should also be performed.

For lockable immersion objectives lock these by
pushing the front part upwards until it stops
(approx. 2 mm). Then, after a gentle turning mo-
tion to the right, the objective is locked.
For objectives with corrective mounts turn the
knurl to adjust the objective to the thickness of
the cover glass.

The magnification of each objective is indicated by a color ring in accordance with DIN/ISO stand-
ards:

Immersion objectives are marked by an addi-
tional, lower color ring.
