Abstract
Hard x-ray beams can be focused using refractive lenses, but depending on energy, a large number N of individual lenses stacked in a row is needed. Such a stack can be either composed of single lenses in cartridges, or lithographically fabricated lenses in a row. With N in the three-digit regime, the question arises which tolerances on lens alignment and shape have to be met not to disturb the focus. Here we use analytical and numerical calculations based on a Zernike polynomial expansion to give such error bounds for typical set-ups.
