LPL25: Tunable Microdoublet Lens Array

We report a novel tunable microdoublet lens capable of creating dual modes of biconvex or meniscus tunable lens. The microlens consists of a tunable liquid-filled lens and a solid negative lens and it can be tuned either by changing the shape of the liquid-filled lens into bi-convex or meniscus or by changing a filling media with different refractive index. The microfabrication is based on soft lithography and photopolymer microdispensing technologies. The microlens can provide a solution for minimizing optical aberrations as well as maximizing the tunability of focal length or field of view since it can change two different lens curvatures.
