System description
General
The Leica M500 N / M520 /M525 surgical microscope is an optical instrument which uses magnification and
illumination to improve visibility. It is dedicated mainly for Neurosurgery discipline.
The microscope is always used together with a Leica stand system – refer to product history on page 1-5.
Electrically the optics carrier and the control unit are connected together to the stand system by the CAN bus.
Newer generations of stand systems (like OH4) have their own MDC (microscope device controller) and take over the
task of the M500 N control unit.
