The FCR-7xx200-2-45 is a reflection probe to get spectral information about powders or highly absorbing fluids. The probe end is simply dipped into the powder or liquid to do the measurements.
Via a standard SMA905 connector light is coupled into a fiber bundle, consisting of 6 fibers and carried to the probe end, where it lights up the material to be analyzed through a silica window under 45 degrees. This angle is necessary to avoid direct reflections from the window. The powder or fluid will selectively reflect light back into a 7th fiber. This fiber transfers the data to the output SMA905 connector, which can be coupled to a spectrometer.
