What Is Near Infrared Spectroscopy?
Near infrared spectroscopy (NIR) is a type of spectroscopy in which the near infrared region of the electromagnetic spectrum is used as an evaluation tool. This technology is used in many different industries, including the pharmaceutical, food and agricultural industries, in certain medical diagnostic tests and in combustion and polymer science. Near infrared spectroscopy is particularly useful in diagnostic medicine because it is capable of recording state changes in hemoglobin, the oxygen-carrying molecule in blood.

Spectroscopy is the study of the way in which matter absorbs and emits light and the way it disperses emitted light into different wavelengths, which are visualized as colors. All types of matter absorb and emit light, and by studying the type of light that is absorbed or emitted, it is possible to gain clues as to the properties of the matter under examination. An object absorbs or emits light of certain colors or wavelengths depending on its temperature, mass, composit
