The spatial resolution of the modem X-ray and neutron detectors is limited by the range of a secondary particles. It was shown theoretically that polycapillary Kumakhov optics can avoid this limit. Such systems can provide resolution less than l#m for energy 17, keV even using ordinary x-rays sources and detectors. The results of experimental investigations of polycapillary cone for imaging of objects with micron level resolution are present. This work is a extension of our last report at SPIE-96. New technology allows us to decrease the entrance capillary diameter to 0.5 micron. On this base we received resolution on the level 1.5 - 2 microns.
