Section: claims

1. An X-ray spectroscopy system, comprising:an apparatus for positioning Bragg diffraction elements, comprising a rigid body that includes:a first planar face having an orientation; anda second planar face having a different orientation than the orientation of the first planar face,wherein the first and second planar faces are configured to position Bragg diffraction elements, and wherein the orientation of the first planar face and the different orientation of the second planar face are arranged to convey a predetermined spectral range of electromagnetic radiation to non-overlapping regions of a sensor array via the Bragg diffraction elements; andan exit spatial filter having an exit aperture configured to select electromagnetic radiation for the non-overlapping regions of the sensor array. 2. The system of claim 1, wherein the distance between a sample to be analyzed and at least one of the first and second planar faces is in the range of about 1 cm to 15 cm. 3. The system of claim 1, wherein the first planar face and the second planar face are arranged such that the non-overlapping regions receive generally the same energy range of electromagnetic radiation. 4. The system of claim 1, wherein the first planar face and the second planar face are arranged such that the non-overlapping regions receive different energy ranges of electromagnetic radiation. 5. The system of claim 1, further comprising a first Bragg diffraction element coupled to the first planar face and a second Bragg diffraction element coupled to the second planar face. 6. The system of claim 5, wherein the first Bragg diffraction element and the second Bragg diffraction element comprise a crystalline material. 7. The system of claim 6, wherein the crystalline material includes diamond, silicon, germanium, and/or lithium fluoride. 8. The system of claim 5, wherein the first Bragg diffraction element and the second Bragg diffraction element comprise a synthetic thin-film multi-layered material. 9. The system of claim 1, wherein the exit aperture is configured to filter a predetermined energy range of the electromagnetic radiation. 10. The system of claim 1, further comprising a sensor array arranged to receive electromagnetic radiation. 11. The system of claim 10, wherein the sensor array comprises a two-dimensional position sensitive detector. 12. The system of claim 10, further comprising a signal processing component configured to output a signal based on electromagnetic radiation detected at the sensor array. 13. The system of claim 12, wherein the signal processing component outputs information describing a spectrum for radiation emanating from a sample. 14. An electron microscopy system comprising the apparatus of claim 1.
