Polycapillary optics are arrays of thousands of hollow capillary tubes. Focal spots are produced from the overlap of outputs from multiple channels at distances of 10–100 mm from the output of the optic. Synchrotron focusing was performed with two

Polycapillary x-ray optics can be used as pre- or post-patient optics to design mammographic imaging systems with higher resolution, greater contrast, and a lower absorbed patient dose. A multi-fiber collimating prototype optic, used as pre-patient b

Polycapillary fibers and a prototype collector for high energy x rays with a 2 m focal length have been fabricated and characterized. Measurements of a prototype collector, performed in collimating mode, show that the optic has high transmission, goo

Polycapillary collimating optics collect x rays produced by a point source over a wide solid angle (as large as 10 - 15 degrees cone angle) and a large energy bandwidth, and provide a quasi-parallel beam with a small divergence (a few milliradians).
