14 DeepView button (depth of field (DoF) management system)
Allows you to optimize the light transmission or depth of field, de-
pending on the application involved. When this function is deactivated
(LED not lit), the microscope is optimized for light transmission. When
this function is activated (green LED is lit), the microscope is automat-
ically set to optimized depth of field in accordance with the selected
magnification. This mode is primarily recommended for procedures on
the anterior segment where high depth of field is required.
The next time the system is switched on, the mode last selected will
be activated.
15 Manual adjustment of the zoom system in the emergency mode
16 Selection knob for different types of illumination
17 Light guide connector
Caution:
Take care not to damage the light guide connector and light guide!
• Always insert the correct end of the light guide into the light guide con-
nector. For correct mounting, please see the label provided under the
light guide connector (17).
Red reflex illumination
This is the best setting to generate an optimum red reflex. Glare
from the sclera is effectively reduced as only the central field of
view is illuminated.
Red reflex with surrounding field illumination
This setting permits clear visualization of the red reflex com-
bined with illumination of the surrounding field of view.
Surrounding field illumination
This setting is used for illuminating the field of view if no red re-
flex is required.
Surrounding field illumination with retina protection device
In this setting, a retina protection device is swung into the sur-
rounding field illumination beam path. It prevents light from en-
tering into the pupil and provides additional protection for the
patient's eye against phototoxic injury.
