摘要 |
An X-ray convergence element and an X-ray irradiation device including the X-ray convergence element are provided. The X-ray convergence element can extend a working distance from an exit-side opening end thereof to a specimen, and can perform analysis of the specimen with rough surface, a fluorescent X-ray analysis, and a X-ray diffraction analysis, regardless of a size of the specimen. An X-ray blocking member 23 is provided with three supporting members 233 for supporting the X-ray blocking member 23, which extend from an annular member 232 having approximately the same diameter as a diameter of an entrance-side opening end (outer diameter of a capillary 20) toward the center of the X-ray blocking member 23 to fix the annular member 232 to the capillary 20. The annular member 232, the supporting members 233, and the X-ray blocking member 23 are integrally formed of a metal that shields X-rays, such as tantalum, tungsten, or molybdenum. A dimension of the X-ray blocking member 23 in the axial direction (thickness) is set to be sufficient for blocking X-rays. |
