Resumo

Hard X-ray (λ ∼ 1 Å) focusing has been realized by a linear phase Bragg-Fresnel lens (BFL) with an efficiency close to 30%. Control of the phase shift of an incident wave on the BFL zone relief has been proposed and experimentally demonstrated by deviating the crystal-lens from the exact Bragg condition.
