Fluidlens is a new type of lens for camera phones. It is made of liquid and it's just as small as a contact lens. However, it promises to offer an optical zoom of up to 10 times by altering its focal length by changing its shape.
“Currently there is no practical alternative to compensate for the fixed focus lens system where a camera lens, for example, is moved along a linear axis until the image comes into focus. Our liquid lens, on the other hand, comprises only a droplet and no other cumbersome movable parts,” explains Dr Saman Dharmatilleke, a research scientist working on the technology.
The Fluidlens will also enable camera cellphone makers to creater slimmer devices with a longer battery life. Check out Digitalcamera101reviews for more details and photo comparisons.
