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.
Claims19
A universal film, quality inspection device comprising:
- a housing;
- a sensitometer located within said housing;
- a light source associated with said sensitometer;
- and
- a densitometer located within said housing, wherein said light source comprises an electrically excitable multicolor luminescent foil.
A method for inspecting the quality of unexposed film comprising the steps of:
- positioning an unexposed film segment in a sensitometer section of a housing;
- electrically exciting a luminescent foil to emit electromagnetic radiations;
- exposing said unexposed film segment in the sensitometer section of the housing to predetermined wavelengths of said electromagnetic radiations and
- measuring the color density or greyness of said exposed film segment in a densitometer section of said housing.
