(a) Schematic showing the IMBUIA optical layout: three flat mirrors (M1, M2 and M3) deliver the IR broadband beam to the IMBUIA-nano station. A movable parabolic mirror (M4) collimates and directs the beam towards the IMBUIA-micro station on demand. M5 focuses the beam and M6 collimates it towards the nanoscope. (Inset) Collimated beam cross-section after M6 at ∼10 m from the source in the visible range (Si CCD camera). (b, c) Simulated and experimental beam cross-section at the M5 position for 633 nm wavelength. Scale bars represent 10 mm. (d, e) Simulation and experiment of the secondary source (SS) after the elliptical focusing mirror (M5) for 1.24 µm and 980 nm wavelengths, respectively. Scale bars represent 10 µm.
