2 Carrier arm for the surgical microscope
The carrier arm incorporates a tilt device. This allows the viewing direction
of the surgical microscope to be adapted to the requirements of the sur-
gical field. Using the knob for fine tilt, you can position the surgical micro-
scope in a range from +90° to -90° (+ in the direction of the surgeon and
- in the opposite direction). The +90° setting is ideal for surgery on pa-
tients in a seated position or lying on their side.
Do not tilt the microscope beyond +/-90°, as this could damage the mi-
croscope cable or the light guide.
3 Surgical microscope
The apochromatic optics of the microscope provide superb optical quality.
The microscope image displays optimum contrast and excellent detail rec-
ognition along with a large depth of field. The bright microscope image is
a particular benefit in vitreoretinal surgery. A 1:6 ratio zoom system allows
the magnification of the overall system to be set as required by the sur-
gical procedure.
Two apochromatic objective lenses with focal lengths of 175 mm and
200 mm are available for different working distances.
4 180° tiltable binocular tube
Due to its large tilt range, the tiltable binocular tube allows optimum ad-
aptation to extreme surgical conditions.
5 Inclined binocular tube (option)
This tube is used as a viewing device for the surgeon. The viewing angle
of 45° allows work with minimum fatigue.
6 Invertertube (option)
The tiltable tube offers an inverter function for ophthalmic applications.
The inverter is used to bring an inverted image created by a wide-angle
observation system into the correct position.
With the inverter deactivated, the tiltable tube has the same optical func-
tion as a normal tiltable tube.
The standard equipment includes eyepieces with a magnification factor of
12.5x (option: 10x).
