Comparison of reconstructed (normalized) intensity profiles of NFP and MMP in the horizontal (a) and vertical (b) direction of the focal plane, for the 100 µm × 100 µm slit setting. Using the series of slit settings we illustrate the dependence of focus size on slit opening for the horizontal (c) and vertical (d) direction. Using the model function equation (9)[link] for the focus width, the size of the source's image is arecon = (182 ± 9) nm × (169 ± 23) nm. (d) Same as (c) with additional and completely independent results for the focus size, as determined by scanning a waveguide (with entrance size 50 nm).
