Abstract
A photometer in which a measuring phase, a reference phase and a dark phase are produced by means of a chopper. These phases are staggered in time, so that a single detector can be provided for all phases. In the photometer the object to be measured is situated between two light conductors, the one light conductor leading to the detector and the other light conductor leading to the chopper input. The chopper output is carried by an additional light conductor to the detector.
