MIT creates a camera lens that can change focus without moving parts

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

Xiaomi working on retractable wide-aperture lens for smartphones

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

From An Eye to an eye: Human Muscles as a Joystick

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

Smaller, cheaper, sharper lenses should be possible as Mexican scientist solves aberration problem

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

Aurora Aperture's revolutionary filter system sits behind the lens

One set of filters for every lens is the promise of Aurora Aperture's revolutionary filter system

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.

Eye-tracking, depth-sensing "autofocal" glasses keep everything looking sharp

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

Lenses For DIY Augmented Reality Will Get a Bit Less Unobtainable

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

Low Cost Optics Bench Project – Now with Lasercut Optics

[PWalsh] has a clever idea for learning and experimenting with basic optics: instead of using actual lenses, he’s using clear pieces of laser-cut acrylic cut into lens profiles instead. They are much easier to make, mount, adjust, and handle while still bending light in the same basic ways. It allows for simple hands-on experimentation with plenty of visual feedback – perfect for beginners.

This idea is part of [PWalsh]’s low-cost optics bench project, which uses laser-cut plastic to create adjustable optics bench components. We’ve covered this project before, but [PWalsh] expanded the idea with the concept of these simple laser-cut …read more
