X-ray focusing lenses with a kinoform profile are high brilliance optics that can produce nano-sized beams on 3rd generation synchrotron beamlines. The lenses are fabricated with sidewalls of micrometer lateral size. They are virtually non-absorbing and therefore can deliver a high flux over a good aperture. We are developing silicon and germanium lenses that will focus hard x-ray beams to less than 0.5 {mu}m size using a single refractive element. In this contribution, we present preliminary optical design and experimental test carried out on ID06 ESRF: the lenses were used to image directly the undulator source, providing a beam with fwhm of about 0.7 {mu}m.
