Diamond lens prototype characterization. (a) Horizontal and (b) vertical differential wavefront gradients measured using a double-crystal monochromator and (c), (d) the associated wavefront gradient error. (e)–(h) Equivalent measurements obtained using a multilayer monochromator. (i), (j) The difference maps of (i) the horizontal gradients and (j) the vertical gradients. (k) The difference phase map calculated using (i) and (j). |
