The New Technologies Shaping Near-Infrared Spectroscopy

Facebook Twitter LinkedIn Email Comments

NIR spectroscopy has evolved from collecting data after the fact to gathering real-time sensor information in the field.

ROBERT V. CHIMENTI, RVC PHOTONICS LLC AND ROWAN UNIVERSITY

Near-infrared (NIR) spectroscopy is the branch of vibrational spectroscopy related to the molecular absorption of light between ~750 to 2500 nm, which has a variety of industrial and medical applications. This region of the electromagnetic spectrum is unique in terms of its interactions with covalently bound molecules because the photon energies in this range are generally too large to correspond to the fundamental vibrational frequencies of a molecule, but too small to result in electronic absorption1.
