CURVATURE DISTRIBUTION CRYSTAL LENS, X-RAY DEVICE HAVING CURVATURE DISTRIBUTION CRYSTAL LENS, AND CURVATURE DISTRIBUTION CRYSTAL LENS MANUFACTURING METHOD

摘要

[PROBLEMS] To provide a curvature distribution crystal lens used in a device performing a structure evaluation by diffraction of a material using X-rays and an analysis evaluation by spectrum and a curvature distribution crystal lens manufacturing method. [MEANS FOR SOLVING PROBLEMS] The curvature distribution crystal lens has a crystal plate of a high yield stress which has been plastically deformed and has a crystal lattice along the curved shape of the surface. The method for manufacturing the curvature distribution crystal lens is characterized in that a load is applied entirely or locally to the crystal plate of a high yield stress at a temperature below the melting point of the crystal so as to plastically deform the crystal plate to have a predetermined curvature.
