Check the following:
• The physician's safety filter (for 532 nm) protects the attending
physician's eyes when looking through the binocular tube of
the operating microscope.
• If an assistant's scope is connected, the physician's safety filter
must be mounted upstream of the beam splitter to the
assistant's scope.
• On OPMI CS operating microscopes, the beam splitter is built
into the body of the microscope. It is therefore not possible to
mount the physician's safety filter upstream of the beam
splitter. If you wish to mount an assistant's scope on the beam
splitter, you must install a second physician's safety filter
between the assistant's scope and the straight binocular tube.
• If the surgical microscope is equipped with an assistant's
microscope, a second physician's safety filter must be built into
the optical path of the assistant's microscope.
