Liquid Lens Can Magnify at the Flick of a Switch

An anonymous reader writes "German engineers have designed the first liquid camera lens with no moving parts that provides two levels of zoom. 'Liquid lenses bend light using the curved boundary between watery and oily liquids. When the two liquids are held in the right container, the boundary between them can be made to curve in a way that focuses light simply by applying a voltage. Liquid lenses have attracted much attention because they are potentially smaller than conventional optics and cheaper to build. Samsung has already built them into some cellphones.'"

I remember seeing this like 5 years ago. I was thinking that it would be pretty cool for telescopes on the moon. This it not even worth checking.

I did this before!
