OPTICAL PROBE WITH SENSOR MADE OF AN OPTICAL POLYMER

摘要

An ATR spectrometer contains an optical probe with a sensor made of a transparent material, a light feeding line and a light carrying-off line. The spectrometer is characterised in that the sensor contains an optical polymer or a mixture of different optical polymers. The probe of the disclosed spectrometer has the advantage of being economical and extremely flexible, so that it may be adapted to the concentration range of the solution to be tested. The existing gap between concentrations that may be measured by conventional transmission spectroscopy and by state of the art ATR spectroscopy is thus closed.
