For example, Tiina Karu, PhD, showed that respiratory chain molecules (such as cytochrome c oxidase) in the mitochondria absorb visible and near-infrared radiation. She then found that radiation absorption increases cellular metabolism, which sends signals to other parts of the cell and spurs growth.
The camera picks up near-infrared radiation, emitted from dedicated units built into the car's headlamp high-beam projectors, when it is reflected off objects directly ahead, up to 25 metres distant.
Contrary to mid-infrared radiation, near-infrared radiation (NIR) shows good transmission for HIPS specimens up to ~1 mm thickness.
It is manufactured by means of a Kubota Research technology (licensed to DuPont-Toray) that uses a P-Wave 2200H-C near-infrared radiation unit.
The first glimmers came from observations of radio waves and X rays, which easily pass through dust, and studies of near-infrared radiation, which can penetrate dust 10 times better than visible-light can.
ISAAC's megapixel detector array is sensitive to near-infrared radiation at wavelengths between 1 and 5 microns (millionths of a meter).
