14 DeepView button (depth of field (DoF) management system)
Allows you to optimize the light transmission or depth of field, depending
on the application involved. When deactivated (LED not lit), the microscope
is optimized for light transmission. When this function is activated (green
LED is lit), the microscope is automatically 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
– Position 1 - Red reflex illumination
This is the best setting to generate an optimum red reflex. Glare from
the sclera is greatly reduced as only the central field of view is illuminated.
– Position 2 - Red reflex with surrounding field illumination
This setting permits clear visualization of the red reflex combined with
illumination of the surrounding field of view.
– Position 3 - Surrounding field illumination
This setting is used for illuminating the field of view if no red reflex is
required.
– Position 4 - Surrounding field illumination with retinal protection device
In this setting, a retinal protection device is swung into the surrounding
field illumination beam path. It prevents light from entering into the
pupil and provides additional protection for the patient's eye against
phototoxic injury.
17 Light guide connector
