In antiquity, we see examples of magnifying crystals formed into a biconvex shape as early as the 7th century BC. Whether the people of that period used them either for …read more Continue reading Lenses: From Fire Starters To Smart Phones and VR
Researchers in China have developed a new type of adaptive liquid lens that changes its focal distance when a voltage is applied. Made using a new electrically responsive fluid, the lens is small, lightweight, and could be easily manufactured for use i… Continue reading Electrically active fluid helps new liquid lens change focus
Traditional lensmaking is a grind — literally. One starts with a piece of glass, rubs it against an abrasive surface to wear away the excess bits, and eventually gets it …read more Continue reading Molding Complex Optics in a Completely Fluid System
Modern zoom lenses work wonderfully, but crack one open and you’ll be greeted by a truly terrifying degree of micro-mechanical complexity, with 20 or more polished glass elements set to move in different directions at varying rates when you work the zo… Continue reading MIT creates a camera lens that can change focus without moving parts
At its annual developer conference last week, Xiaomi announced an upcoming wide-aperture lens that retracts into the body of a smartphone when not in use, promising long optical zoom without increasing the girth of our ubiquitous mobile companions.Cont… Continue reading Xiaomi working on retractable wide-aperture lens for smartphones
The interface between humans and machines has been a constantly evolving field. Sure the computer mouse was a game-changer, but time moves on. We are now looking at integrating machines via soft HMIs for personal applications. A research team led by the University of California, San Diego has presented a …read more

One of the oldest problems in optics has been solved. Rafael Gonzalez from the Tecnologico de Monterrey has come up with an almost comically dense equation that can be used to almost completely eliminate spherical aberration in optical lenses… Continue reading Smaller, cheaper, sharper lenses should be possible as Mexican scientist solves aberration problem
Lens filters are an important tool for many DSLR photographers, but dealing with different diameter lenses, stepping-rings, square filter mounts and the rest can be frustrating and expensive. But now, an ingenious filter system for mirrorless camera adapter mounts looks to shake everything up – except your photos.

No matter how good your eyesight, there’s a decent chance that it’ll start to fade at a certain point in your life. Presbyopia is a common form of age-induced far-sightedness, where the lenses in the eyes become stiff and have trouble focusin… Continue reading Eye-tracking, depth-sensing "autofocal" glasses keep everything looking sharp
You may remember that earlier this year Leap Motion revealed Project North Star, a kind of open-source reference design for an Augmented Reality (AR) headset. While it’s not destined to make high scores in the fashion department, it aims to be hacker-friendly and boasts a large field of view. There’s also an attractive element of “what you see is what you get” when it comes to the displays and optical design, which is a good thing for hackability. Instead of everything residing in a black box, the system uses two forward-facing displays (one for each eye) whose images are …read more
