Core throughput within a photometric aperture of radius 0.7λ/D at 500 nm (left panel) and 1000 nm (right panel) shown in units of angular resolution (where the effective diameters are D^on-axis = 5.25 m and D^off-axis = 5.36 m, respectively). The angular separation of an exo-Earth if viewed at 12 pc, at orbital quadrature at 83 mas is shown with a green dashed line. The exo-Earth can be efficiently imaged across the entire 500–1000 nm band.
