Reflection probes are used to obtain spectral information of diffuse or specular materials. The light from a light source is sent through six illumination fibers to the sample, and the reflection is measured by a 7th fiber in the center of the reflection probe tip. The 7th fiber is coupled to a spectrometer configured to the appropriate wavelength range of interest. More illumination fibers can be added to get more energy from the light source and therefore increase the reflection signal level.

The FCR-COL is an adjustable UV/VIS/NIR collimating and focusing lens, which enables focusing the measurement spot at an extended distance.
