(a) Intensity profiles isolated from ambient light and measured along the aa’ line for $z\mathrm{\hspace{0.17em}\hspace{0.17em}}=\mathrm{\hspace{0.17em}\hspace{0.17em}}55$, 75, 95, 115, 135, 155, and 175 mm. DC alignment is indicated in read and IC in green. (b) Idem to (a) but for the bb’ line. (c) Idem to (a) but with additional ambient light. (d) Idem to (b) but with additional ambient light.
