Abstract
On the light radiation device X6A side, a box structure is provided in which a lens is held one by one proximate to or close to the light emission end of each optical fiber. On the light source device side, a common casing houses a first light source lens that generally collimates the radiation light beams radiated from an LED and a second light source lens that condenses the light beams from the first light source lens and introduces the condensed light beams to the light introduction end of the optical fiber bundle. Thus, the current demands of tests on a piece of work can be fully satisfied in view of the light condensing area and the light condensing efficiency while making the best of the characteristics of the illumination system in which the light radiation device and the light source device are separated with an intervention of the optical fibers.
