Abstract
A method based on the combination of elastomeric molding and optofluidic technologies is proposed to realize the integration of pneumatically actuated variable aperture into a lens component for miniature optical systems. The main feature of the assembly is the self-aligning property between lens and aperture. All the structures are fabricated onto a polydimethylsiloxane (PDMS) substrate and the prototype is experimentally demonstrated to possess the self-aligning characteristic without requiring any tuning mechanisms. At the same time, additional tunability of the lens focal length can also be easily obtained with this design concept.
