Reflection Probes
The FCR-7xx200-2 is a standard reflection probe to get spectral information of diffuse or directly reflecting or backscattering materials.
Via a standard SMA905 connector, light from a light source is coupled into a fibre bundle consisting of 6 fibers and carried to the probe end. The surface will selectively reflect light back into a 7th fibre. This fibre transfers the data to the output SMA905 connector which can be coupled to a spectrometer or spectrum analyzer. A higher number of fibres are possible to couple more energy from the light source and to increase the signal level.
For measurements under 90º, the FCR-90-Option, a special adapter with a mirror under 45º was developed. This can easily be mounted onto the tip of the reflection probe. The FCR-COL is available to focus the measurement spot on an extended distance.
