Patent ID: 7403593

Claim:
An x-ray optical apparatus for conditioning an x-ray beam, the apparatus comprising: a total reflection section comprising a material with an index of refraction less than unity at a selected wavelength of the x-ray beam, the material having a polished surface that receives and redirects the beam; and a multilayer section comprising alternating material layers that are spaced relative to each other such as to provide wavelength specific reflection at the selected wavelength of the x-ray beam and corresponding monochromating of the x-ray beam, wherein the total reflection section and the multilayer section are arranged relative to each other such that the x-ray beam encounters the polished surface of the total reflection section at an incidence angle low enough to provide total external reflection of the beam, and encounters the multilayer section at a Bragg angle that provides peak reflection of the selected wavelength, and wherein substantially all portions of the x-ray beam at the selected wavelength are redirected by both the total reflection section and the multilayer section along a predetermined path.
