The width W of the beam profile at the screen versus the eccentricity e. The left-hand and right-hand parts show data for e < 1 and e > 1, respectively. The direction of the left-hand horizontal axis is reversed. The insets show the shape of the lenses of the same radius of curvature p = 200 µm and e = 0.3, 1 and 1.8 from left to right. |
