AI Article Synopsis
- High-performance fluidic lenses can adjust focal lengths from 30 mm to infinity without moving the lens position.
- The lens's focal length, F-number, and numerical aperture can be dynamically controlled by changing its shape.
- The lenses have a nearly perfect spherical profile and achieve resolutions of over 40 line pairs/mm for plano-convex and 57 line pairs/mm for biconvex structures.
Article Abstract
High-performance fluidic lenses with an adjustable focal length spanning a very wide range (30 mm to infinite) are demonstrated. We show that the focal length, F-number, and numerical aperture can be dynamically controlled by changing the shape of the fluidic adaptive lens without moving the lens position mechanically. The shortest focal length demonstrated is less than 30 mm for a 20-mm lens aperture. The fluidic adaptive lens has a nearly perfect spherical profile and shows a resolution better than 40 line pairs/mm in a plano-convex structure and 57 line pairs/mm in a biconvex structure.
