Ultra-low cost tuneable lens
Conventional rigid lenses can only create changes in focal plane (focus) and focal length (zoom) by using multiple lens elements, often in multiple groups. However a single element flexible lens (typically made from liquids or polymers) can do this on its own. Researchers at the University of Cambridge have developed a way of manufacturing ultra-low cost flexible lenses which are highly robust, with few if any moving parts, from non-toxic materials. These lenses should be suitable for a broad range of applications across different market sectors.
