Reflection Probes with multiple legs
For some measurements, a reflection probe is required that can be coupled to two spectrometers and a light source. A good example is a reflection measurement in the UV/VIS and NIR range. For these situations, we offer our reflection probes with multiple legs.
The light from a light source is coupled into a fibre bundle, consisting of 17 illumination fibres which transport the light to the end of the probe. The reflected light is uniformly reflected into the two read (detection) fibres, each of which is connected to a spectrometer. In the example of a UV/VIS and NIR configuration, a mix of high OH UV/VIS fibre and low OH VIS/NIR fibres are used for the respective light wavelengths and spectrometer types.
For measurements under a 90° angle, the FCR-90-Option has been developed. It is an adapter with a mirror mounted at 45° and can be easily mounted to the tip of these reflection probes.
To accurately focus a small measurement spot from a higher distance, the FCR-COL adjustable US/VIS/NIR collimating/focusing lens is available and can be mounted to the tip of these probes.
Other lengths and fibre types are available. Specify xx = UV for UV/VIS fibre cables, IR for VIS/NIR and UVIR for broadband UV/VIS/NIR
