Abstract: There is disclosed an optical radiation sensor system. The system includes a sensor device (140) and a cleaning device (115). The sensor device detects and responds to radiation from a radiation field (170) and includes a surface (155) that is movable with respect to the radiation field between a first position in which the surface is in the radiation field and a second position in which at least a portion of the surface is out of the radiation field. The cleaning device operates to remove fouling materials from at least a portion of the surface in the second position. The cleaning device may be a chemical cleaning device, a mechanical cleaning device or a combined chemical/mechanical device.
