ABSTRACT:
The inside of a casing of a multiunit tube is divided into two chambers by a partition wall. The partition wall is formed with an opening through which light is transmitted. A deuterium lamp for emitting ultraviolet light, and a tungsten lamp for emitting visible light, are disposed in the first and second chambers, respectively. The casing is formed, on its first-chamber side, with a window, through which the ultraviolet and visible lights from the lamps are let out. The opening is fitted with a filter for reducing the liminous intensity of the visible light from the tungsten lamp.
