Figure 1
Top: proposal for an X-ray monochromator based on a prism array half lens, in which tuning is provided by rotating by angle [alpha] around an axis y orthogonal to the incident beam as shown. Only the illuminated prisms in an off-axis prism lens are drawn. Bottom: decomposition of the prisms in the illuminated area into two structures, which perform optically identically.  [article HTML]
