Tiny Flexible Laser On A Chip Created By Liquid Lens

Like tiny Jedi knights, tunable fluidic micro lenses can focus and direct light at will to count cells, evaluate molecules or create on-chip optical tweezers, according to a team of Penn State engineers. They may also provide imaging in medical devices, eliminating the necessity and discomfort of moving the tip of a probe. Conventional, fixed focal length lenses can focus light at only one distance.
