Table 1. Summary of the main parameters from the metrology of the Be lenses used in the simulations.
The bottom rows display the accumulated figure errors calculated by propagating a plane wave through the system; the accumulated figure errors weighted with the system transmission at 8 keV; and the quadrature summation of the individual r.m.s. values from L01 to L10.
