The resolution of Fresnel zone plate (FZP) as X-ray lens is determined by the width of outer-most zone, and the diameter of condenser lens is desirable to be large so that bright x-ray beam is available in x-ray optical systems. As the diameter of FZPs with nm resolution reported so far is small...
