Paraboloidal beryllium (Be) lenses and their characterization. (a) Schematic of the lens (left) with an enlarged view (right) mounted in a holder. (b) Schematic of the experimental setup for phase-contrast imaging of Be lenses in the transmission geometry (Qiao et al., 2021BB38). (c) The reconstructed thickness profile T(x, y) of one of the best Be lenses. (d) The thickness residual error after removing the best-fit parabola from (c).
