Abstract
An optical sensor device includes a photoconductor structure having first and second partial members () and a coupling surface () for coupling the optical sensor device to an opposing counter surface of a pane (), particularly a windscreen of a motor vehicle. The optical sensor device further includes an optical transmitter () coupling a beam of rays into the first partial member (), an optical receiver () receiveing a beam of rays emerging from the second partial member (), and a printed circuit board () arranged parallel to the coupling surface (). The transmitter () and the receiver () are arranged on the printed circuit board (). The photoconductor structure is designed so that the central ray () of the transmitter () enters into the first partial member () perpendicularly to the coupling surface () and emerges from the second partial member () perpendicularly to the coupling surface ().
