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.
5.1 Interactance Reflectance Configuration
The Interactance Reflectance barrel should be
screwed onto the probe for reflectance sampling.
This photo shows the sample window, which is
faceted to illuminate the sample, and to channel
reflected energy back to the detectors.
Always be sure the probe barrel is screwed tightly,
against the metal stop. Do not scratch or damage
the Smart Probe window.

Method (DCM) in Vision.
