Adjusting the surgical microscope and laser micromanipulator to
the same focal plane
The OPMI Vario is equipped with a motorized Varioskop zoom system
which is operated via the focusing buttons of handgrip (1) or the foot con-
trol panel.
The Varioskop is used for the motorized setting of the working distance
(coarse focus) and the motorized adjustment of image definition (fine
focus). The focusing buttons allow you continuous adjustment of the
working distance between 200 mm and 415 mm.
•
Set the working distance (coarse focus) to the focus value of the laser
micromanipulator. The display shows the focus value currently set.
•
Use the previously described, recommended procedure to check that
the focal planes coincide.
•
If necessary, correct the focus by appropriate minor adjustment (fine
focus).
Focus stop button (2) permits you to deactivate the electrical drive of the
focusing system. The focus stop button is lit. This prevents the setting
from being inadvertently changed by the motorized function.
