The latest achievements in manufacturing and investigations of polycapillary optics in Russia are reviewed. For the first time one succeeded in creating the polycapillary lens with focal spot diameter lesser than 10 micrometers . Combination of these lenses with a small portable microfocus source of 100 W power allows to obtain the x-ray photons concentration more than 10(superscript 5) photons/s micrometers (superscript 2). Such density is comparable with density obtaining at the synchrotron beams with E equals 1 GeV and 0.1 A current. This result is a revolutionary one for a number of applications, e.g., for diffractometry, x-ray analysis, x-ray microscopy, etc. On the base of a halflens and new 10 W microfocus tube of 10 micrometers size the space-saving source emitting parallel x-rays with brightness of the order of 10(superscript 10) photons/s mm(superscript 2) had been created.
