On the following pages we compare our polynomial fit to raytraced ground truth for other lenses than the ones shown in the pa-per. For each of the lenses we tested, there is a drawing of the lenssystem with ray traced rays (grey) and the evaluated polynomial(coloured). Ideally these two should match on both the apertureand the outer pupil.Another plot shows the Fresnel transmittance for both ray tracedrays and the fitted polynomial on the outer pupil for each lens.
