Using 3D printing and porous silicon, researchers at the University of Illinois Urbana-Champaign have developed compact, visible wavelength achromats that are essential for miniaturized and ...

On a late night in February 2011, two Princeton University researchers packed a small object into a box and set it out for the morning mail. The engineers had spent four years developing a new type of ...

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 engineers. They may also ...

A University of Utah team have a working prototype of a new twist on fluid-filled lenses for correction of vision problems: automatic adjustment and refocus depending on what you’re looking at.

August 19, 2005 Taking a leaf from Mother Nature, scientists at A*STAR’s Institute of Materials Research and Engineering (IMRE) in Singapore have developed tiny lenses made of liquid, which mimics the ...

Using two immiscible fluids, each with a different refractive index, the liquid lens FluidFocus technology from Philips (Amsterdam, The Netherlands) can create unique variable-focus lenses of high ...

Researchers at Rensselaer Polytechnic Institute (RPI) have created an adaptive liquid lens that captures 250 pictures per second. Because these lenses are simply powered by water and sound, they need ...

Ever heard of Liquid Lens Technology? No? That’s fine. We will explain. Liquid lens technology was developed more than two decades ago by French physicist Bruno Berge. Unlike a lot of cameras that use ...

Rafe Needleman reviews mobile apps and products for fun, and picks startups apart when he gets bored. He has evaluated thousands of new companies, most of which have since gone out of business. In ...

Holography is about capturing 3D data from a scene, and being able to reconstruct that scene — preferably in high fidelity. Holography is not a new idea, but engaging in it is not exactly a ...
