4.4.2 Cleaning Optical Output Terminal
4.4 Cleaning
• The mating portions of the laser output connec-
tor ferrule and of the connector adapter are
high-precision machined parts. Make sure that
these portions are free of dust or other foreign
matter when connecting them. In particular, the
optical output connector ferrule requires meticu-
lous care. If there is dust in the interface or a
scratch on the optical output connector ferrule,
the 3662-20/3663-20 may not satisfy perfor-
mance specifications.
• When cleaning the optical output connector,
make sure that power to the laser source is off.
While power is on, do not look directly into the
connector or look at it through a magnifying
glass. The laser beam may damage the eye.
The laser beam is not visible.
