2. Near-infrared
Science & Engineering · Physics Abbreviations
Shortest-wavelength part of the infrared, just beyond visible red light, commonly about 750 to 1,400 nanometers (some definitions extend to 2,500). NIR light passes through tissue and many materials, so it is used in pulse oximeters, fiber-optic communications, night-vision illuminators and food and pharmaceutical analysis.
Example: NIR spectroscopy measures protein and moisture in grain samples in seconds.
Telecommunications fibers carry signals at 1,310 and 1,550 nanometers, in the near-infrared, where glass absorbs least. Pulse oximeters compare absorption of red and near-infrared light to estimate blood oxygen. The James Webb Space Telescope's NIRCam instrument images the universe in the near-infrared.
