Controls on the microscope
1 DOF button (DeepView depth of field management system)
for selecting between optimum light transmission and maximum depth
of field. 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 the optimum depth of field in
accordance with the selected magnification. The next time the system
is switched on, the mode last selected will be activated.
2 Zoom adjustment knob for manual mode
for manual controlling the zoom system.
3 Illumination knob
for selecting the illumination mode:
– 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,
providing additional protection for the patient’s eye against phototoxic
damage.
4 Light guide connector
Always make sure to insert the correct end of the light guide into the light
guide connector. For correct mounting, please see the label provided
below the light guide connector.
