capture and hold the incoming light briefly before releasing it again. In the same way that a traditional glass lens would, these precisely tuned delays change the direction of the light, but without the optical aberrations seen in conventional lenses. In fact, its creators say the lens produces...
Centuries of effort to improve imaging has focused on perfecting and combining lenses to obtain better optical performance and new functionalities. The arrival of nanotechnology has brought to this effort engineered surfaces called metalenses, which prom
It can be helpful to have aneyeglasses repair kitbecause these kits usually have small screwdrivers, replacement screws and a magnifying glass. Some also have replacement nose pads. You can buy an eyeglasses repair kit online or at a pharmacy or retail optical store. ...
I really don't understand the "buy the most expensive camera, use the cheapest glass" mentality. As if the lens is a camera accessory and not part of the camera. Well, I have a decent collection of cheap vintage lenses that work fine for me. I don't have any superb lenses, but on...
Google partners with Diane Von Furstenberg to offer fashionable DVF Google Glass. Source: Google Google was the first major technology company to release a head-worn computer when it introduced Google Glass in 2013. It cost $1,500 at the time, and was explicitly targeted at people in the com...
