1/2" Industrial Reflection Probes for Powders and Thick Fluids

The FCR-7xx200-2-45-IND is a heavy-duty reflection probe with exchangeable tip to get spectral information about powders or thick 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.
