The OPMI CS-NC surgical Microscope
and the NC2 Floor Stand
form an optimum instrument combination which is specially
adapted to the requirements of neurosurgery.
The innovative design of the OPMI CS-NC opens up new
possibilities for the surgeon. Various Microscope
can be attached to the interface on the underside of the
body. The component of interest here is the
Varioskop, which allows adjustment of the working distance
between 200 mm and 400 mm before and during a surgical
procedure. The Microscope
need not be set to a fixed working
distance, but can be positioned to ensure maximum
convenience for the surgeon.
The Variospot is another component, whose illuminated field
can be adjusted from the size of the field of view to a spot
of 11 mm diameter (at objective focal length f = 200 mm).
The Combilux is a component providing automatic brightness
adjustment when the magnification is changed. Separate
manuals are available for the individual Microscope
Further features of the Microscope
Motorized focusing and zoom action; convertible from a
for one surgeon to a Microscope
for two surgeons
sitting face to face; attaching of stereo coobservation
tube. 35 mm camera and video camera.
The system for adjusting the tilt angle between the
and the Microscope
carrier arm is motorized.
The NC2 Floor Stand is equipped with solenoid brakes which
prevent inadvertent changes to the position of the
microscope. The brakes can be disengaged by pressing the
respective buttons, thus enabling weightless positioning of
. The balancing system is semiautomatic.
The xenon lamp of the Superlux 300
source provides a color temperature equivalent to that of
daylight. The high light intensity can be reduced as
required or briefly increased when the camera is triggered
for documentation purposes. The lamp housing incorporates a
100 W halogen lamp as a back-up illumination system. The
light is supplied to the Microscope
via a light guide.
This instrument configuration has been designed for
neurosurgery and is also suitable for other fields of
microsurgery, with the exception of ophthalmology.
The automatic leveling system is offered as an optional
function for the NC2 Floor Stand. The automatic leveling
system is used to level the NC2 Floor Stand when it is
standing on an unlevel surface. It can compensate for
gradients of up to 1° with an accuracy of ±2' (arc minute) .
The automatic leveling system is necessary when the NC2
Floor Stand is used on an unlevel floor and the Microscope
must be positioned using a mouth switch.
The OPMI CS-NC and the NC2 Floor Stand can function as a
system when used together with the
micromanipulator MM 6 with automatic focal
component Varioskop The working distance in this
system can be varied between 200 and 400 mm without changing
