23 Mar 2012 Adaptive polymer based optics can provide a smart, low-cost, yet high-quality alternative to traditional optics. Using a liquid polymer, Optotune has developed a range of focus tunable lenses - offering freedom and flexibility to optics designers.
A change in lens radius of several micrometers can have the same optical effect as moving the entire lens several centimeters. Optical systems can thus be designed to be more compact, often with fewer lenses, and usually with less or no translational movement meaning no more need for expensive mechanical actuators. Less movement also leads to a more robust design, which can be completely closed so that no dust can enter.
The materials employed are all lighter than glass, saving overall weight. Less movement and weight also means less power consumption and faster response times, in the order of milliseconds.
