Simulated HEW as a function of the focus shift Δf2 for a Gaussian source of waist radius w0 = 180 µm. The vertical K–B is considered. (a) Ideal mirror profile, wavelength as input parameter (see legend). (b) Ideal mirror profile. (c) Real mirror profile. Color code for (b) and (c): green – source at Δf1 = 0, λ = 20 nm; purple – source at Δf1 = −11.25 m, λ = 20 nm (radiator III); orange – source at Δf1 = 0, λ = 10 nm. Solid lines: source on-axis emission at Δϑ = 0. Dashed lines: source off-axis emission at Δϑ = −10 µrad. |
