Abstract

An apparatus for the optoelectronic classification of semiconductor materials, has a separating device 2 and a slide face 3, the angle of the slide face 3 to the horizontal being adjustable, and the separating device 2 and the slide face 3 each having a surface made of the semiconductor material to be separated. There is a radiation source 5, through the beam path of which the material to be classified falls, and a shape recognition device 6, which transmits the shape of the material to be classified to a control unit 7, which controls at least one diverter device 8.
