Figure 3
Hierarchical depiction of the CRL. (a) A single thin element equivalent to several lenslets. This representation accounts for net refraction and absorption in one transmission element but ignores intra-lens spacing. (b) Multi-slice representation of a CRL. Here each lens of the stack is represented individually by one transmission element. Those are separated by a drift space corresponding to the typical distance between elements (Δs). (c) Not only can the CRL be represented as a series of thin elements separated by drift spaces, but figure errors can also be added. They are placed directly after the thin element representing a single X-ray lens.
