The FCR-7xx200-2 is a standard reflection probe to get spectral information of diffuse or directly reflecting or back-scattering materials.
Via a standard SMA905 connector light from a light source is coupled into a fiber bundle, consisting of 6 fibers and carried to the probe end. The surface 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 or spectrum analyzer. A higher number of fibers 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, which can be easily mounted on the tip of the reflection probe. The FCR-COL is available to focus the measurement spot on an extended distance.
