An optical device comprising a sealed/closed housing; a light source and/or a detector within the housing; a window through the housing that is transparent to light transmitted from the light source or to the detector and a fixing for fixing an optical fiber or bundle of such fibers into a coupling position adjacent to the window to allow light to pass between the housing and the fiber or fiber bundle, wherein the fixing is adapted to allow connection and/or disconnection of the fiber or fiber bundle without opening or breaking a seal of the sealed housing. |
