ABSTRACT:
An optical detector is disclosed, which is adapted to measure the opacity of media. The detector comprises a light means and a light sensor, arranged so as to have a media path there between. The light source has a drive means, which is actively adjustable, during use, for detecting media of different opacities, so as to maintain a substantially constant sensor output.
