A summary of focusing X ray polycapillary optics is presented including history, theory, modeling, and applications development. The focusing effects of polycapillary optics come from the overlap of the beams from thousands of small hollow glass tubes. Modeling efforts accurately describe optics performance to allow for system development in a wide variety of geometries. The focusing of X ray beams with polycapillary optics yields high gains in intensity and increased spatial resolution for a variety of clinical, lab-based, synchrotron or in situ analysis applications.

“…For the quantitative analysis of a sample using confocal XRF based on PXRO, a few methods have so far been developed , Schmitz et al 2009, Sun et al 2009b, Sun et al 2010, Fittschen and Falkenberg 2011, Mazel et al 2011). The fundamental parameter approach assuming a spherical probing volume has been proposed for the analysis of paint layers.…”

“…For example, confocal XRF spectrometers with a PFXRL in the excitation channel and a PPXRL in the detection channel base on the conventional X-ray source can be designed under air condition (Sun et al 2010, Cordes et al 2014). There are certain limitations for such confocal XRF spectrometers under air condition, namely, it cannot detect XRF of low-atomicnumber elements due to absorption of low-energy X-ray photons by ambient air.…”

Capillary X-ray optics is versatile, and it can be used with synchrotron radiation source, conventional X-ray source, laser-plasma ultrafast X-ray source, and so forth. Recently, the confocal X-ray technology based on capillary X-ray optics has become popular, and it has been widely used in X-ray fluorescence, X-ray absorption fine structure, X-ray diffraction, small-angle X-ray scattering, X-ray imaging, and X-ray scattering. This confocal X-ray technology has applications in many fields, including environmental monitoring, food science, life science, chemistry, physics, nanomaterials, nondestructive test, security check, and so on.

“…Of course, it also enables a depth elemental profiling. There are many reports of depth elemental profiling for layered materials such as paint layers [29][30][31][32][33][34][35][36][37][38][39]. The author's research group at OCU has reported a depth elemental profile for car paint chips, which have several layers depending on the type of car and manufacturing process [40].…”
