To obtain spectral information of diffuse, or specular materials, reflection probes can be used.

 

The light from a light source is sent through six illumination fibres to the sample and the reflection is measured by a 7th fibre mounted in the centre of the reflection probe tip. This 7th fibre is coupled to a spectrometer configured to the appropriate wavelength range of interest. More illumination fibres can be added to get more energy from the light source and therefore increase the reflection signal level.

​

For measurements under an angle of 90°, the FCR-90-Option was developed. It’s a special adapter with a mirror positioned at 45° and can be easily mounted on the tip of our standard reflection probes.

​

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