Probes, light guides & diffuse optics
The right accessories for your application.
To record the color readings, a probe must be placed at the extruder exit. For this purpose, the extruder insert - consisting of a sleeve with sapphire glass at the top - screwed into a threaded hole. The melt flowing over the field of view thus provides an insight into the liquid material. In the extruder probe, a high-temperature resistant optical fiber is used, by means of which light is emitted into the material and the light reflected from the material is returned to the color evaluation.
Both parts in this functional unit are exposed to the extreme conditions of temperature and pressure and dimensioned accordingly.
Furthermore, a diffuse 8 degree optic with gloss trap is available to determine the degree of transmission or reflectance. The design complies with the specifications of the DIN 5036 standard for diffuse reflectance measurements, the inner part - procure like an integrating sphere - consists of barium sulfate. With the exchangeable gloss trap, you determine whether or not the directional radiation component is to be taken into account in the measurement.
