Figure 8
The double-diffracted beam intensity distribution on the focusing plane in a RDL with a beryllium lens. Shown are the cases corresponding to magnifications M = 1 (a), M = 1.5 (b), M = 0.5 (c). The beam falls at the Bragg-corrected angle corresponding to the wave with [\Delta\lambda/\lambda_{\rm{m}}] = 0. Absorption in the lens is neglected. Numerical integration by formula (76)[link]. Point source.
