Abstract
An x-ray optical filter includes at least one x-ray optical mirror configured to receive a plurality of x-rays having a first x-ray spectrum with a first intensity as a function of energy in a predetermined solid angle range and to separate at least some of the received x-rays by multilayer reflection or total external reflection into reflected x-rays and non-reflected x-rays and to form an x-ray beam including at least some of the reflected x-rays and/or at least some of the non-reflected x-rays. The x-ray beam has a second x-ray spectrum with a second intensity as a function of energy in the solid angle range, the second intensity greater than or equal to 50% of the first intensity across a first continuous energy range at least 3 keV wide, the second intensity less than or equal to 10% of the first intensity across a second continuous energy range at least 100 eV wide.
