(a) SEM image of the opaque mask with five apertures at the vertices of a pentagon inscribed in a circle with a diameter of 20 µm. (b) Left column: experimental interference patterns obtained at λ = 1.59 nm (778 eV) using the n = −1, 0, +1 diffraction orders of the FG (f = 1, p = 600 nm). Right column: calculated patterns for an incoming beam with L = −1, 0, +1.
