Abstract
A semiconductor sensor includes a detector chip that detects green light and an interference filter that optically precedes the detector chip and is permeable to green light and impermeable and reflective to red light and near-infrared radiation. A color filter optically precedes the interference filter. The color filter has a transparency of at least 60% for green light and has an absorbing effect for red light and near-infrared radiation. The semiconductor sensor appears gray or black in the region of the interference filter independently of the angle.
