How does the icon analyser work?
The analyser uses visible light produced by a 12V 10W tungsten lamp running under reduced voltage to increase its life. Light passes out of the analyser enclosure through an optical window and along a fibre-optic cable to an external measuring cell. The light enters the cell through another window fitted with a focusing lens. It then passes through the test sample and out via a further window and fibre-optic cable back into the enclosure and to the dispersive spectrometer module, where the optical transmission or absorbance measurements at 2048 wavelengths are carried out. These measurements are fed into a control computer which calculates the final results.
