The high resolution, high asymmetric diffractive x-ray lens was tested at BM5 beamline in ESRF.The lens consists of two Si(111) channel-cut crystals in dispersive arrangment with the angle of asymmetry of 12.7 o . The channels have a circular profile with the diameter of 22 mm. The test was performed for the energy of 7.8-8.1 keV and the focusing distance of 19-20 m.
