The Korea Research Institute of Standards and Science (KRISS, President Ho Seong Lee) has successfully developed a high-quality compound semiconductor material for ultra-sensitive SWIR sensors.

Radiation within the visible spectrum can appear black if it is low in power ... Photons outside that range of wavelengths are invisible to human eyes. Shorter wavelength energy includes ultraviolet, ...

The temperature continued rising further in the area behind the red end of the spectrum. Ultimately, he discovered the maximum temperature point far beyond the red area. Today this area is known as ...

Every chemical compound absorbs a unique set of wavelengths of light ... reflects near-infrared light—the so-called red edge, invisible to human eyes but easily observable with infrared ...

F OR SOLDIERS at the front, electromagnetic defences are as vital as air: invisible when present, and disastrous when not. In ...
