The human eye does not actually see purple, as purple is not a color on the visual spectrum. Purple is a combination of wavelengths from opposite extremes of the spectrum, which technically deosn't ...

A new molecule developed by Ohio State University scientists can harvest energy from the entire visible spectrum of light, bringing in up to 50 percent more solar energy than current solar cells, and ...

Curved lenses, like those in cameras or telescopes, are stacked in order to reduce distortions and resolve a clear image. That's why high-power microscopes are so big and telephoto lenses so long.

Researchers have developed the first standard LED covering the full visible light, in collaboration with Nichia Corporation. LED and OLED lighting, which is generally called solid-state lighting (SSL) ...

The use of CMOS sensors for capturing images in the visible spectrum is extensively used. They are affordable and can be integrated within various applications, as their form factors are adaptable to ...

Researchers have demonstrated the first planar lens that works with high efficiency within the visible spectrum of light -- covering the whole range of colors from red to blue. The lens can resolve ...
