Humans see light at the lower end of the visible spectrum, having a longer wavelength, about 740 nm, as red; we perceive light in the middle of the spectrum as green; and see light at the upper ...

The materials currently used for photocatalysis are either transparent to the visible light spectrum (for example ... light illumination of Pt-loaded WO3 nanotubes. 1 The key was using Pt ...

In an experiment to measure the difference in temperature between the colors in the visible spectrum, he placed thermometers in the path of light within each color of the visible spectrum.

Meta-lens works in the visible spectrum, sees smaller than a wavelength of light High efficiency ultra-thin planar lens could replace heavy, bulky lenses in smart phones, cameras and telescopes ...

A research team led by Jie Chen from Xi’an Jiaotong University has developed a novel visible-light-driven (λ > 420 nm) Z-scheme heterojunction photocatalyst composed of 0D Cs₃Bi₂I₉ ...

Although this range is still officially known as the 'visible spectrum', the advent of lasers with very specific infrared wavelengths brought reports that people were seeing laser light with ...

The researchers evaluated their miniaturized optical spectrometer in a series of tests and found that it achieved remarkable results, operating across the entire visible spectrum regime (~400 ...

This technology has been really well developed, but only in the visible spectrum, leaving untapped opportunities for technologies in both the ultraviolet and infrared regions of the ...

The Harvard School of Engineering and Applied Sciences (SEAS) has developed the first single lens that can focus the entire visible spectrum of light — including white light — in the same spot and in ...

A series of coated lenses can allow people to see ultraviolet light superimposed onto the visible spectrum, extending the range of our senses without the need of electronic devices. UV imaging can ...
