Embodiment Construction

[0034] The optical device in the embodiment of the present invention includes a plurality of solid components, each solid component is made of glass material, and the side wall is coated with a metal film. The critical surface of the glass material and the metal film forms a reflective surface. One of the two ends of each solid member is used to receive X-rays, and when the X-rays pass through the reflective surface, total reflection occurs, and the other end outputs X-rays. A plurality of solid components jointly realize the micro-convergence of divergent X-rays. The embodiment of the present invention improves the effect of transmitting high-energy X-rays by increasing the density of the reflective material. The optical device in the embodiment of the present invention can converge X-rays above 40keV, especially 40-120keV X-rays. And the smoothness of the glass material is used to ensure the transmission efficiency of X-rays in the optical device. At the same time, the opti...

Abstract

The invention discloses a combined X ray microfocus optical device that is used for transforming high energy divergent X beams into X beams with the divergence being 0.5-2 degrees and filtering low energy X rays. The optical device is of axial symmetry structure, and an outline bus along axial direction is the combination of a quadratic curve segment and a straight line segment; the optical devicecomprises a plurality of solid members and X rays diverged in a microfocus manner through the plurality of solid members; the solid members are made from glass material, and the side wall is plated with a metal film; the glass material and a critical surface of the metal film form a reflecting surface, and total reflection occurs when X rays pass through the reflecting surface; and one of two ends of each solid member is used for receiving X rays and the other end is used for outputting X rays.

Description

technical field [0001] The invention relates to the field of optics, in particular to a combined X-ray micro-converging optical device. Background technique [0002] X-rays are electromagnetic waves with a shorter wavelength than ultraviolet rays, and are widely used in physics, chemistry, life science, material science, astronomy, environmental science, medicine and other fields. However, because the wavelength of X-rays is too short, people have been unable to change its propagation direction before the 1980s. To obtain high power density X-rays, the power of X-ray generating equipment must be increased. In the late 1980s, the former Soviet scientist Kumakhov proposed an optical device composed of multiple hollow glass capillary tube bundles, which can adjust the transmission direction of X-rays in a large angle and wide band according to people's requirements. Such optical devices are known as capillary X-ray lenses. The invention of this technology is the first time in...
