A proximity sensor assembly including a light source, a first detector, and a first light focusing device. The light source is operative to emit light toward a first target area. The first detector is operative to detect light, including light emitted by the light source and reflected from the first target area. The first light focusing device is in a first optical path between the light source and the first detector. The first optical path includes an optical path from the light source and reflected from the first target area.
