Tunable and latchable liquid microlens with photopolymerizable components
05 June 2003
A novel liquid microlens with photopolymerizable components is described (see Figure). When the lens is in liquid form, both its position and curvature can be reversibly tuned through electrowetting. After the liquid microlens is precisely aligned on the substrate, it is exposed to UV light to initiate polymerization and thus lock its position and shape.
