2006/02/07 Rementeria Argote, Nagore - Elhuyar Zientziaren Komunikazioa

This is a new liquid lens that only acts on the pressure of the change of focus. The lens is a curved interface between the air and a liquid, located in a small opening.

It was carried out in Singapore by physicists of the Institute of Engineering and Materials Research (IMRE). And they have explained that this lens does not need mechanical parts and because of its small size is very suitable for tools that carry some small camera, such as webcams, mobile phones or portable tools of doctors.
