Dear Confocal users,

        I am looking for a method to protect the fiber optic cable of our
soon to be purchased Leica TCS/SP/MP system.  The system normally comes
with a 5W Millennia and a pico second Tsunami (TI:sapphire) with a mirror
set for 720-850nm wave lengths.  I want to get the 10W Millennia for
additional power when using the less efficient mirror set for 850-990nm
wavelengths.  This new system will be in a multi user facility located in a
medical school / hospital setting and I am concerned about someone using
the 10W Millennia to send too much power through the fiber when using the
more  efficient 720-850nm mirror set thereby damaging the optical fiber.
        What I want to do is to insert a shutter in to the light path
before the beam enters the fiber cable.  I want this shutter to be
connected to a monitoring devise so when the power of the beam from the
Tsunami exceeds a safe limit, the shutter will close before damage occurs
to the fiber cable.  Does anyone know of an off-the-shelf system from an
optical or laser company that can do what I want?

        Any help or suggestions on other fail-safe methods would be
appreciated.

Thanks,
        Will
