Function Effect
Light status The following status options are available:
• [On]: OPMI light is switched on following
activation of the device setting.
• [Off]: OPMI light is switched off following
activation of the device setting.
• [Standby]: OPMI light is in standby mode
following activation of the device setting. Only
available if a xenon lamp is installed for the OPMI
light on your device. In standby mode, the lamp
is switched on, but blocked out. This prevents
flickering of the light which occurs on ignition of
the xenon lamp.
Light intensity The light intensity can only be adjusted for the
auxiliary lamp if [On] is selected as the initial state.
Filter The selection of filters depends on which filters are
installed. It is also possible to select [Without] for no
filter.
3.5.4 Total magnification
The total magnification is a function of the zoom value and the
optical parameters on the eyepieces, tube and lens. The zoom value
is not directly set on the device; rather, it is adjusted via the total
magnification settings. When the total magnification is changed,
the zoom adjusts so that the device zoom/eyepieces/tube/lens
produce the set total magnification.
3.5.5 Fast focus
Fast focus is used to quickly switch between two different focus
levels. This might be necessary if IOL is used or an Endo light sensor
is implemented. When fast focus is activated, the surgical
microscope moves from its current focus position upward and
away from the eye according to the value set (max. 40mm or to
the respective stop). Activating fast focus again returns the focus to
its initial position. The focus will not return to its initial position if
the following actions are performed following activation of fast
focus:
• The device is restarted
• A magnetic brake is released
• The user profile is switched
• The surgery profile is switched
• The XY Reset button is pressed
The "fast focus" function can only be activated by means of the 14-
function foot control panel or the handgrips. This requires config-
uring the 14-function foot control panel or the handgrips to do so.
