If you need a lens for a project, chances are pretty good that you pick up a catalog or look up an optics vendor online and just order something. Practical, …read more Continue reading The Ins and Outs of Casting Lenses from Epoxy
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
Researchers at Princeton and the the University of Washington have developed a tiny camera, the size of a grain of salt, which can snap sharp, full-color images. It’s made with a metasurface that captures light, which could be scaled up to turn entire … Continue reading Tiny salt-grain-sized camera snaps hi-res full-color images
We found a couple of headlines this week that seemed pretty alarming at first, mentioning as they did both “Chinese grannies” and “stun guns.” Digging a little deeper, it appears …read more Continue reading Hackaday Links: October 17, 2021
Quantum computers have the potential to drastically outperform traditional computers, but for now they’re mostly limited to labs and big experimental setups. Japanese researchers have now made a step towards more accessible quantum computing devices, f… Continue reading Twisted light makes for breakthrough quantum computer chip
Magic mirrors, with an LCD panel hidden behind a partially reflectively mirror, are popular for a reason — they’re a good-looking way to display useful information. A “Magic Window,” however, …read more Continue reading Math, Optics, and CNC Combine to Hide Secret Images in Acrylic
A Bayer array, or Bayer filter, is what lets a digital camera take color photos. It’s an array of tiny color filters that sit on top of a camera’s CCD. …read more Continue reading Using a Laser to Blast Away a Bayer Array
The world record for fastest internet speed has been utterly shattered as Japanese engineers have demonstrated a data transmission rate of 319 Terabits per second (Tb/s) through optical fibers. The record was set over more than 3,000 km (1,864 miles) o… Continue reading Data transmission speed record clocks blistering 319 Terabits per second
When it comes to inspiring a lifelong appreciation of science, few experiences are as powerful as that first glimpse of the world swimming in a drop of pond water as …read more Continue reading Lego Microscope Aims to Discover Future Scientists
A quantum internet could one day allow quantum computers to team up and tackle some gigantic problems. Now the world is a step closer to that reality, as researchers at Toshiba have demonstrated quantum communications sent over a record-breaking 600 km… Continue reading Toshiba breaks quantum communication record with 600 km of optical fibers
