In the field of near-infrared (NIR) spectroscopy, a system that combines portability with the accuracy and functionality of high-performance laboratory systems would significantly enhance real-time analysis. The development of small handheld spectrometers, powered by a battery, could lead to more efficient monitoring of industrial processes or assessments of food ripeness in the field. Spectroscopy is used to evaluate the chemical makeup of items in the lab and the field. Courtesy of Texas Instruments. Most dispersive IR spectroscopic measurements begin in the same manner.
