Kinoform lenses with various groove heights. The lens profile in (a) does not have perfectly uniform groove heights due to finite samplings. The zone widths vary from 10.4 to 41.8 μm in (c), from 7.8 to 34.6 μm in (d), from 7.8 to 36.6 μm in (e), from 11.7 to 47 μm in (f), and from 17.6 to 55.4 μm in (g). Figures of phase space share the color bar in (b). The parameters for the incident light source are σ = 5 μm, δ = 0.7 μm and M = 40
