Zusammenfassung:A sensor system configured to determine a position of a substrate having an edge. The sensor system includes a radiation source arranged to emit a radiation bundle, a reflective element, a detector device and a substrate table having a supporting surface for supporting the substrate. The supporting surface is at least partly along a plane. The radiation source and the detector device are arranged on a first side of the plane. The reflective element is arranged on a second side of the plane other than the first side. The reflective element is arranged to create a reflected bundle by reflecting the radiation bundle. The reflective element is arranged to illuminate the edge with the reflected bundle. The detector device is arranged to receive the reflected bundle.
