Estimating the term…
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.
A light radiation device for radiating onto a radiation object site a light beam introduced via an optical fiber bundle made of a plurality of optical fibers, the light radiation device having a box that houses a fiber holding section for holding a light emission end of each of the optical fibers in a discretely disposed state and a lens holding section for holding a lens one by one proximate to or close to the light emission end of each of the optical fibers.
A light source device for supplying a light beam via a light guiding member such as an optical fiber bundle made of a plurality of bundled optical fibers or a glass rod, the light source device having a common casing that houses a first light source lens for collimating radiation light beams emitted from a single or a plurality of LED(s) into generally parallel light beams and a second light source lens for condensing the light beams from the first light source lens to introduce the condensed light beams to a light introduction end of the light guiding member.
A light source device for supplying a light beam via an optical fiber bundle made of a plurality of bundled optical fibers, wherein
A light connection mechanism provided with a light passageway having a circular cross-section for passing a light beam and a reflection/refraction section disposed on an outer peripheral surface of the light passageway for reflecting or refracting the light beams inward, wherein end surfaces of the light passageway are disposed respectively proximate to or close to an end surface of an optical fiber bundle on a light source device side and an end surface of an optical fiber bundle on a light radiation device side with coincident axial centers, and a diameter of the light passageway is set to be generally equal to a diameter of each of the optical fiber bundles.
