Researchers at the Dalian University of Technology and the University of Hong Kong have developed a novel method for creating dynamically reconfigurable color displays using Tamm plasmonic photonic ...

Researchers in Quebec, Canda, have developed the first fiber laser that can produce femtosecond pulses in the visible range of the electromagnetic spectrum. Fiber lasers producing ultrashort, bright ...

The human eye can only see light at certain frequencies (called the visible spectrum), the lowest of which constitutes red light. Infrared light, which we can’t see, has an even lower frequency than ...

The 6W AR111 4D LED lamp is the first full visible spectrum 4-degree AR111 LED lamp. The LED lamp features a peak intensity of 12,600 cd for the VIVID series and 15,900 cd for the BRILLIANT series. It ...

Have you ever wondered what the invisible world of radio waves might look like if you could actually see it? Rootkid explains how his project, the Spectrum Slit, transforms the unseen chaos of ...
