Ray-tracing simulations of an optical X-ray system based on a
spherically bent crystal operating in Bragg configuration for
monochromatic projection imaging of thin samples are presented,
obtained using a code developed for that purpose. The code is
particularly suited for characterizing experimental arrangements
routinely used with laser-produced plasma X-ray sources. In particular,
the spatial resolution of the imaging system was investigated and a
careful study of the complex pattern of the X-ray backlighting beam was
performed.
