A soller slit is disclosed, which includes a plurality of metal foils and functions to restrict divergence of X-rays when arranged on an X-ray optical path. The metal foils are prepared by sintering a metal material such that surface thereof have high harmonic surface roughness. Alternatively, the metal foil has oxides formed by oxidation on the surfaces thereof such that the oxides can provide the high harmonic surface roughness. The high harmonic surface roughness of the metal foil restricts total reflection of X-rays at the metal foil. Therefore, it is possible to form high precision parallel X-ray beams by the soller slit to thereby improve resolution in an X-ray measurement. <IMAGE> |
