near-infrared radiation
near-in·fra·red radiation (nîr′ĭn′frə-rĕd′)n. Electromagnetic radiation having the shortest wavelengths in the infrared region, often considered to be between approximately 0.75 and 2.5 micrometers. Also called near-red radiation.near-infrared radiation
near-infrared radiation[′nir ‚in·frə′red ‚rād·ē′ā·shən] (electromagnetism) Infrared radiation having a relatively short wavelength, between 0.75 and about 2.5 micrometers (some scientists place the upper limit from 1.5 to 3 micrometers), at which radiation can be detected by photoelectric cells, and which corresponds in frequency range to the lower electronic energy levels of molecules and semiconductors. Also known as photoelectric infrared radiation. near-infrared radiation
