PROBLEM TO BE SOLVED: To irradiate a living body with one kind of light which is selected from among UV-rays and a plurality of exciting lights obtained by the wavelength conversion of UV-rays, as the exciting light. SOLUTION: A photographic stage 13 is provided with a housing 25, in which a bottom part light source 15 emitting UV-rays is arranged, wavelength converting filters 28-30 and recognizing switches 31 and 32. The wavelength converting filters 28-30 are respectively attached to the housing 25 via rotation axes 28a, 29a and 30a and freely revolved between a wavelength converting position where UV-rays are respectively converted to red, blue and green fluorescences, to have the living body irradiated and the retraction position retracted from the wavelength converting position. It is recognized that one among the wavelength conversion filters 28-30 is set at a wavelength conversion position, or that all of them are not set at the wavelength conversion position by the on-off signals of the recognizing switches 31 and 32.
