Abstract
An optical sensor device for the detection of ambient light is adapted to be coupled to a pane (10), in particular to a windshield of a vehicle. The optical sensor device has a sensor unit which includes at least one light receiver (22) for ambient light and a lens plate (12) for directionally coupling an ambient light beam (26) out of the pane (10) onto the light receiver (22). The lens plate (12) has a surface (18) facing the light receiver (22) and oriented substantially parallel to the pane (10) in the coupled condition of the optical sensor device. The surface (18) includes a prism structure (20) having a plurality of single prisms (24) which are designed to direct the rays of a specific ambient light beam (26) defined by a principal direction (A) and an aperture angle onto the light receiver (22).
