An example of a three-level nickel zone plate with 200 µm diameter and effective 200 nm smallest zone width (top). The marked regions can be seen below with higher magnification, showing the individual steps of 2/3 and 1/3 fill factor at the center and at the edge of the zone plate. The effective smallest zone width is the half-period of 200 nm.
