A light source is positioned outside the first window for directing light through the product stream, and the spacing between the windows is adjusted to control the length of an optical path through the product stream. A detector is positioned outside the second window for receiving light passing along the optical path, and a photometric calibration filter is removably installed between the second window and the detector for calibration of the system.
