The FCR-14xx200-2-REF is a special reflection probe to get spectral information of diffuse or direct reflecting materials.
The reference leg was added to be able to correct fluctuations of the lightsource by a second spectrometer channel.
Via a standard SMA905 connector light is coupled into a fiber bundle, consisting of 12 fibers. These 12 fibers are split into 2x 6 fibers, 6 fibers carried to the probe end and 6 fibers reflecting on white diffuse material inside the coupler, then back reflecting into 1 fiber of the reference leg, connected through an SMA905 connector to the slave channel of the spectrometer. The probe end will selectively reflect light back into a 7th fiber. This fiber transfers the data to the output SMA905 connector, which can be coupled to the master channel of the spectrometer.
