8. Operation

Note:Note:

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.
