摘要： In a measuring device for capturing ambient light for use in a motor vehicle, having a light-sensitive detector and an optical element, which is provided and formed to direct ambient light onto the detector, it is essential to the invention that the optical element has an outer lateral surface, a light entry side and a light emission side and that at least one of the two sides, light entry side or light emission side, has a curved surface. The curved surface is at least partially roughened and has a higher roughness than the lateral surface of the optical element.
