Description

(1) Technical field [0001] The invention belongs to an X-ray microstructure optical device, in particular to an X-ray combination lens, which is suitable for one-dimensional focusing and imaging of high-energy X-ray wave band (>5keV) radiation. (2) Background technology [0002] X-ray combined lens is a new type of X-ray microstructure optical element suitable for high-energy X-ray band (that is, X-ray radiation energy exceeding 5keV) proposed by A. Snigirev in 1996. The X-ray combination lens has many advantages, such as no need to bend the optical path, good high temperature stability and easy cooling, simple and compact structure, and low requirements on the surface roughness of the lens. Therefore, this component is considered to have broad application prospects in scientific and technical research. In recent years, research on various X-ray diagnostic techniques based on X-ray combined lenses is very active. For example, high-energy X-ray fluorescence micro-tomogra...
