A Poly-CCC (Poly Capillary Conic Collimator) is an X-ray poly capillary optics with a conically shaped basic form. Divergent X-rays are collimated and guided. For instance it is possible to collect fluorescence radiation emitted from the sample surface and guide them to a detector. The sketch shows schematically the principle use of a Poly-CCC for XRF or PIXE.
