Figure 8
Refraction efficiency e for the focusing of X-rays depending on the off-axis position y in lenses (from left to right) 35/1/SU8, 35/1/pmma and 35/2/pmma. The dots are the measured points, the thin line is the simulation by use of (47) and the thick lines are the expected refraction efficiencies for perfect lens segments. While the solid line is the expectation inside the optimum aperture size, the dotted line refers to the prediction outside this aperture. |
