Abstract
A detector for back-scattered electrons includes a scintillator crystal and a light-conducting device for directing away the secondary radiation to a receiver. The light-conducting device is placed against the scintillator crystal in such a way that the secondary radiation is directed away symmetrically to two lines of symmetry. The two lines of symmetry are located in the plane of the scintillator crystal and are at right angles to one another. In this way, a uniform illumination of the scanned image is obtained.
