Section: claims

1. An X-ray focusing device comprising:a multi-capillary lens comprising a plurality of bundled capillaries for guiding X-rays, wherein at least one end face of said multi-capillary lens is a converging end for concentrating and irradiating X-rays to a micro-area located outside of the end face; anda single-capillary lens comprising one capillary for guiding X-ray, wherein at least one end face of said single-capillary lens is a converging end for irradiating X-ray to the micro-area located outside of the end face where the micro-area is smaller than the irradiation area of the X-ray converged by the multi-capillary lens, and the other end face is a long-focal length converging end or a parallel end capable of accepting parallel X-ray beams where the long-focal length converging end or the parallel end has a focal length that is longer than the focal length of the converging end of the single-capillary lens for irradiating X-ray, andwherein the parallel end or the long-focal length converging end of said single-capillary lens is positioned outside the converging end of said multi-capillary lens, and said multi-capillary lens and said single-capillary lens are positioned so that the optical axis of said multi-capillary lens at the converging end coincides with the optical axis of the single-capillary lens at the parallel end or the long-focal length converging end. 2. The X-ray focusing device according to claim 1, wherein the single-capillary lens is a substantially tubular shape with a tapered tip at the converging end. 3. An X-ray focusing device comprising:a multi-capillary lens comprising a plurality of bundled capillaries for guiding X-rays, wherein at least one end of said multi-capillary lens is a converging end for concentrating and irradiating X-rays to a micro-area outside of the one end; anda single-capillary lens comprising one capillary for guiding X-ray, wherein a first end of said single-capillary lens is a spheroid-shaped converging end with a short-focal length for irradiating X-ray to the micro-area outside of the first end, and a second end, opposite to the first end, is a spheroid-shaped converging end with a long-focal length, opposing the one end of the multi-capillary lens, whereby the second end of the single-capillary lens has a focal length that is longer than the first end of the single-capillary lens for irradiating X-ray, andwherein the second end of said single-capillary lens is positioned outside the converging end of said multi-capillary lens, and said multi-capillary lens and said single-capillary lens are positioned to have the optical axis coincide.
