Abstract
A sensor apparatus for mounting on a motor vehicle window for determining the position of the sun includes at least one lens body and at least one detector with photosensitive regions, wherein the lens body has a radiation entry side and a radiation exit side which faces the detector. The sensor apparatus is wherein an opaque structure is arranged inside the lens body, at least four lens sections of the lens body are defined by the opaque structure, a photosensitive region of the detector is assigned to each lens section, and each lens section has at least one convex lens contour on the radiation exit side of the lens body.

A sensor apparatus for mounting on a vehicle window for determining the position of the sun, wherein the sensor apparatus has at least one lens body and at least one detector with photosensitive regions, wherein the lens body has a radiation entry side and a radiation exit side facing the detector, wherein
- an opaque structure is arranged inside the lens body,
- at least four lens sections of the lens body are defined by the opaque structure,
- a photosensitive region of the detector is assigned to each lens section, and each lens section has at least one convex lens contour on the radiation exit side of the lens body,
- wherein the opaque structure is constructed in the form of a cross with four cross arms, that a lens section of the lens body in the form of a quadrant is formed between each two adjacent cross arms of the cruciform opaque structure,
- wherein at least portions of the cross arms of the cruciform structure are wedge-shaped,
- wherein the vertices of the acute angles defined between the wedge faces are situated on the outer sides of the structure at the outer ends of the cross arms.
