摘要
X-ray fluorescence (XRF) spectroscopy systems and methods are provided. One system includes a source of x-ray radiation and an excitation optic disposed between the x-ray radiation source and the sample for collecting x-ray radiation from the source and focusing the x-ray radiation to a focal point on the sample to incite at least one analyte in the sample to fluoresce. The system further includes an x-ray fluorescence detector and a collection optic comprising a doubly curved diffracting optic disposed between the sample and the x-ray fluorescence detector for collecting x-ray fluorescence from the focal point on the sample and focusing the fluorescent x-rays towards the x-ray fluorescence detector.
