Abstract
A moisture sensor which registers the amount of moisture from tear-shaped precipitation, particularly on a windshield. The device includes a beam director which is mounted on the windshield by an optical adhesive. The beam director has a beam transmitter on one side and a beam receptor on the other. To ensure an optically perfect attachment of the beam director as an integrated unit to the windshield, there is a parallel relationship between the windshield and the facing surface of the beam director. An optical adhesive is applied to the gap between the windshield and the beam director, and is confined to a particular area.
