Polycapillary X-ray optics for micro XRF and XRD
In this application note, XOS describes the features and benefits of the polycapillary X-ray optic solutions for X-ray fluorescence and X-ray diffraction, aimed to significantly enhance the performance of X-ray analysis.
The evolution of polycapillary optics
The advances of the polycapillary X-ray optics have made it a must-have optical component in high-end X-ray analytical instruments for pioneering industrial applications like micro XRF. The optics have also been successfully used in synchrotron radiation facilities for research in micro X-ray analysis (XRF and X-ray absorption spectroscopy). Other unique applications include confocal XRF analysis and super-conducting EDS detectors.
Enhancing Micro XRF Analysis with Polycapillary Optics
X-ray fluorescence (XRF) is a commonly used technique for elemental analysis. Compared to other technologies, XRF is non-destructive, easy to use, and requires minimal sample preparation. Micro-XRF applies the same principles as XRF but on a much smaller (micro) scale.
The Evolution of Polycapillary Optics
The concept of polycapillary optics was introduced in the late 1980’s. During this time, XOS and a few other groups around the world conducted extensive research and development to significantly improve the optic manufacturing process. As a result, XOS became a leading global manufacturer of highperformance X-ray polycapillary optics and excitation systems. Today, polycapillary X-ray optics are used as key components in high-end X-ray analytical instruments and have dramatically enhanced system performance.
