The invention relates to a detection device for identifying objects in a material stream, preferably a cullet stream. The device comprises several light sources, which emit light in a rectilinear manner, preferably diode light sources and which are combined to form at least one optical emitter, at least one receiver that contains a lens system and a photoelectric cell, in addition to a detection section, which is located between the emitter and the receiver and is traversed by the material stream. The aim of the invention is to provide a detection device, which eliminates to a great extent the error sources that are inherent in optical lens systems. To achieve this, the light sources of an emitter are directed onto the area of intersection of the optical axis of the lens system with the lens system of the receiver that is assigned to the emitter.
A detecting apparatus (5) for detecting objects in a material flow, preferably consisting of cullet, with several light sources (7) radiating light in a straight line, preferably diode light sources, being combined into at least one optical transmitter unit (6) and with at least one receiver unit (8) being provided which comprises at least one lens system (9) and photocell (18) and is associated with the at least one transmitter unit (6), as well as an interposed detecting section (4a) which is flowed through by the material flow, wherein the light sources (7) of a transmitter unit (6) are aligned to the region of the point of intersection (S) of the optical axis (20) of the lens system (9) with the lens system (9) of the receiver unit (8) associated with the transmitter unit (6).
