Abstract
The parameters of two elliptical poly-capillary lenses and one mono-capillary parabolic lens were characterized at the optical test bench of the BM05 ESRF beamline and at the BESSY μFocus beamline. The poly-capillary lenses with an input aperture of ∅ 5–6 mm have shown a focal spot size (FWHM) on the order of 6–20 μm with a gain factor of about 600–700 in a wide energy range. For the first time the parabolic mono-capillary lens has shown a focal spot size of <2 μm in the energy range of 10–15 keV. The gain factor reached 980.
