Abstract
The invention relates to a device for universal quality inspection of material to be exposed, especially of technical films and x-ray films, using an exposure means designed as a sensitometer, and a densitometer, which are combined into a single device. A densitometer is combined with a light source for individual measurements for determining the behavior of the density curve of a film with a densitometer designed as a measurement arm. A luminescent film which can be excited in two colors and which lies in one plane is used as a light source for the sensitometer.
