A sealed housing (10) for housing a camera (100) is configured to exclude the atmosphere external to the sealed housing away from the camera. The sealed housing has a viewing portion through which light can pass to reach the camera inside the sealed housing, and the viewing portion comprises a viewing window (50) and a protective window (40). The protective window forms an outside surface of the sealed housing, and the viewing window is spaced apart from the protective window and forms an internal surface of the sealed housing. Preferably the windows are made of germanium. |
