Earlier, and perhaps more basic, LED masks usually provide just one primary colour treatment mode, such as red or blue, ...

A new filter for infrared light could see scanning and screening technology tumble in price and size. Built on nanotechnology ...

The new lens can reportedly focus light just like a traditional glass lens, and cut the wavelength of the incoming light in half, effectively shifting infrared light into the visible spectrum.

With higher efficiency and lower costs, perovskite–silicon tandem cells mark a breakthrough in solar tech. Can they truly ...

The new lens can reportedly focus light just like a traditional glass lens, and cut the wavelength of the incoming light in half, effectively shifting infrared light into the visible spectrum.

According to NASA, near infrared light is closer in wavelength to visible light (the colors we can see with our naked eye), which means its wavelength is shorter than FIR.

The human eye lacks photoreceptors responsive to the infrared spectrum, and infrared light with a longer wavelength and lower energy cannot trigger visual signals. In patients with severe eye diseases ...

Infrared (IR) light-emitting materials have wide applications. However, variety and economical accesses to obtain IR materials and devices are still limited, because the IR-emitting materials are ...

We present a brief description of the activities of the infrared astronomy group of Tata Institute of Fundamental Research with special emphasis on the near-infrared instrumentation for star formation ...

New research shows how light can be bent, focused, and even changed in color using structures so small they’re invisible to the eye. 'Magical' ultra-thin lenses transform infrared light into ...

Using the Very Large Array (VLA), astronomers have performed radio observations of a galaxy cluster Abell 2744, nicknamed ...

We demonstrate a novel white-light light-emitting-diode (LED) structure that operates at infrared wavelengths for broadening optical bandwidth performance. The nonuniform carrier distribution problem ...
