The coated sphere under Köhler illumination (NA 0.6/0.2, field stop 25 µm): against a cone average of plane waves Köhler illumination is incoherent across the pupil, so a sphere sees an average of plane waves over the illumination cone; the reference does that average with the plane-wave cross sections and the amplitude matrix.
