Abstract
A sensor device for detecting moisture on a windscreen has a transmitter and a receiver and optics arranged between the transmitter and the receiver. The optics have an upper plane for connection to a windscreen, a decoupling region serving to decouple the electromagnetic rays from the optics into the windscreen, and a coupling region serving to couple the electromagnetic radiation from the windscreen into the optics, and which even for a small construction shall supply a usable signal. The decoupling region has at least one surface inclined relative to the upper plane of the optics.
