How to clean instruments with an optical glass plate
E Cleaning Information
Never try to open the instrument and clean the optical
block by yourself, because it is easy to scratch optical
components, and cause them to be misaligned.
How to clean instruments with
an optical glass plate
Some instruments, for example, the optical heads from
Agilent Technologies have an optical glass plate to protect
the sensor. Clean this glass plate in the same way as
optical lenses (see "How to clean lenses" on page 289).
How to clean instruments with a
physical contact interface
Remove any connector interfaces from the optical output
of the instrument before you start the cleaning procedure.
Microscope
Cleaning interfaces is difficult as the core diameter of a
single-mode fiber is only about 9 µ m. This generally
means you cannot see streaks or scratches on the surface.
To be certain of the degree of pollution on the surface of
your interface and to check whether it has been removed
after cleaning, you need a microscope.
W A R N IN G
Never look into an optical output, because this can
seriously damage your eyesight.
