Industrial Transmission Process Probe With Variable Pathlength

For the measurement of absorbance and transmission in rough conditions, this probe is equipped with variable Dip Tip which enables the end-user to adjust the optical pathlength of 0.5mm up to 20mm. Illumination happens with a collimated beam through the sample onto a special backcoated mirror, the reflected light beam passes back through the sample once more and is coupled into the read fibre for connection to the spectrometer/detector.
