Patent ID: 7242746

Claim:
A method for manufacturing a reflector for X-ray ray radiation having a curved substrate and a multi-layer coating deposited on the substrate, the method comprising the steps of: a) determining a first non-circular arc shape for the substrate along a first cross-section, extending in an XZ plane containing an X direction; b) determining, following step a), a d-value dependence that satisfies Bragg's condition in the X direction; c) determining, in a YZ plane containing a Y direction perpendicular to the X direction, a deviation from a uniform coating dependence that results from a method of deposition of the coating, for a circular substrate shape in the YZ plane; d) determining a second non-circular arc shape for the substrate along a second cross section, extending in the Y direction to compensate for the deviation determined in step c) by bringing regions of the reflector where coating deviations in the Y direction occur into Bragg reflection for a desired wavelength; and e) producing the reflector following steps a) to d), wherein the mirror focuses, renders parallel, or otherwise optically aligns the X-ray radiation in both the X and Y directions using one single reflection.
