Reflection Probes with Reference

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 fibre bundle, consisting of 12 fibres. These 12 fibres are split into 2x 6 fibres. 6 fibres are carried to the probe end and 6 fibres reflect on white diffuse material inside the coupler. Then back reflecting into 1 fibre of the reference leg which is connected through an SMA905 connector to the slave channel of the spectrometer. The probe end will selectively reflect light back into a 7th fibre. This fibre transfers the data to the output SMA905 connector which can be coupled to the master channel of the spectrometer.
