Abstract :
A tunable aperture stop based on optofluidic technology is presented. Using the high absorption of aqueous pigment dispersions, we demonstrate that this approach may be used to define optical stops of high contrast. Our highly flexible design is based on photolithographic patterning of dry film resist and allows control of laminar flow in microfluidic chambers.
