摘要：A sensor for checking value documents, which has an illumination device for illuminating a value document, an imaging optic and a detection device. The illumination device of the sensor contains a multiplicity of light sources arranged side by side, which have emission spectra that differ from each other, and a microlens array with a multiplicity of microlenses. The microlens array and the light-source receiver are arranged so that when each of the light sources is arranged on the light-source receiver there is associated therewith exactly one of the microlenses. The measuring plane of the sensor is so close to a focal point of the imaging optic that the light of the different light sources emitted by the illumination device is largely imaged onto the same illuminated region of the measuring plane.
