Focal length tunable fluidic adaptive lens

In this presentation, we demonstrate a fluidic adaptive lens inspired by animal eye´s crystalline lens that can be deformed by muscles to adjust its focal length. Fluidic adaptive lenses, which can adjust their focal length by changing the shape or index without moving parts, are attractive. In summary, we have demonstrated a fluidic lens with an adjustable focal length over a very large range. The bio-inspired fluidic adaptive lens shows great promise for significant size, weight, cost, and complexity reduction compared to conventional solid lenses.
