Novel system mimics focus activity of the human eye

With aging comes deteriorating vision. At SIGGRAPH 2018, attendees will have the chance to test a new computational system that effectively mimics the natural way the human eye corrects focus, specifically while viewing objects ...

Delivering VR in perfect focus with nanostructure meta-lenses

If wearing a virtual reality or augmented reality headset is ever to become commonplace, hardware manufacturers will need to figure out how to make the devices small and lightweight while ensuring their images are sharp and ...

Metalens achieves near-unity numerical aperture

Researchers have designed an optical lens with the highest free-space numerical aperture to date, achieving a value of just under 1. As the numerical aperture indicates the highest possible resolution that a lens can attain, ...

Sharpening the X-ray view of the nanocosm

A novel lens offers scientists the sharpest X-ray images yet from the nano world. The device is made from alternating layers of tungsten carbide and silicon carbide and can focus hard X-rays into a spot of less than ten nanometers ...
