OptiProbe Module
The XDS™ OptiProbe Analyzer is designed for sampling of many types of customer samples. This
section describes removal of the protective barrel, and handling of the fiber bundle.
The OptiProbe is shipped with a blank end, to
protect the fiber optic termination.
Unscrew this end and remove it. Place the end into
the wooden box, which contains the Interactance
Reflectance and Interactance Immersion ends.
If the OptiProbe is ever shipped to another
location, the blank end should be used to prevent
damage.
The proper sampling end should be installed, as
described in these sections of the manual:
Interactance Reflectance: 5.1
Interactance Immersion 5.2
Always be sure the barrel is screwed down fully
before sampling. The black O-Ring should not be
visible when fully assembled.
Failure to tighten the probe barrel will cause the
instrument to fail diagnostic tests, and will cause
spectral distortion.
The fiber optic bundle, while well-protected,
should always be handled with care. The individual
fibers are quite thin, and can be broken by rough
handling. Breakage of these strands will reduce the
light energy, and will eventually cause the
instrument to fail diagnostic tests.
Always observe these precautions:
• Never bend the bundle tighter than a 12”
(305mm) diameter. As a rule, do not bend
the fiber any tighter than the gentle bend
that it assumes in a normal repose.
• Always store the bundle on the holder
when not in use.
• Never attempt to “stretch” the fiber
beyond its reach.
Fiber bundle lengths are 2-meter and 3-meter.
