Zeiss S7 / OPMI VISU 160 Instructions For Use Manual

System Overview S7 / OPMI VISU 160Version 6.0Page 52 G-30-1528-en2 Carrier arm for the surgical microscopeThe carrier arm incorporates a tilt device. This allows the viewing directionof 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 microscopeThe 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 isa particular benefit in vitreoretinal surgery. A 1:6 ratio zoom system allowsthe 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 and200 mm are available for different working distances.4 180° tiltable binocular tubeDue 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 angleof 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-angleobservation 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 of12.5x (option: 10x).
