Abstract: In a sensor apparatus, in particular a sensor apparatus for detecting ambient conditions of a motor vehicle, wherein the sensor apparatus comprises at least one screen which predefines the detection angle of the sensor apparatus and a detector and wherein an optical component is disposed between the screen and the detector, a greater detection angle is to be achieved. This is achieved whereby the optical component has at least one first and one second concavely curved region, the first inner region is disposed adjacent to the optic axis, where the second region surrounds the first region and that the first region has a stronger concave curvature than the second region.
