Figure 12
X-ray beam intensity profile as measured 25 mm upstream of focus, at focus, and 25 mm and 50 mm after the focus. Top row: 10 × unpolished diamond lenses. Middle row: 10 × polished diamond lenses. Bottom row: 11 × beryllium lenses. Note that the colour range is different for each column and has been plotted using a power law with exponent 0.33 (gamma correction) in order to highlight less-intense regions.
