2 Support arm for the surgical microscope
The support arm incorporates a tilt device (3). This allows the viewing
direction of the surgical microscope to be adapted to the requirements
of the surgical field. Using the knob for fine tilt, you can position the
surgical microscope 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 patients in a seated position or lying on their side.
Caution:
Do not tilt the microscope beyond + / -90°, as this could damage the
microscope cable or the light guide.
3 Knob for tilt device
4 Surgical microscope
The apochromatic optics of the surgical microscope provide superb
optical quality. The microscope image displays optimum contrast and
excellent detail recognition 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 surgical procedure. Two apochromatic objective
lenses with focal lengths of 175 mm and 200 mm are available for dif-
ferent working distances.
5 Invertertube for the main surgeon
6 Invertertube for the assistant
Tubes (5) and (6) offer 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, tubes (5) and (6) have the same optical
function as normal tiltable tubes.
7 180° tiltable binocular tube (option)
Due to its large tilt range, the tiltable binocular tube allows optimum
adaptation to extreme surgical conditions.
8 45° 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.
The standard equipment includes eyepieces with a magnification factor of
10x (option: 12.5x ).
