Dependence on photon energy of the lens gap 2g in SRLs with focal length of f = 1 m according to (7) (top) and of the optimum lens length 2AL (bottom), where AL is the attenuation length of the materials, for lighter materials, which were used in transmission lenses for X-rays, i.e. lithium (Li), beryllium (Be), plexiglass (PMMA), aluminium (Al) and silicon (Si). |
