Abstract

Abstract: This review article focuses on the principles and applications of miniaturized near‐infrared (NIR) spectrometers. This technology and its applicability has advanced considerably over the last few years and revolutionized several fields of application. What is particularly remarkable is that the applications have a distinctly diverse nature, ranging from agriculture and the food sector, through to materials science, industry and environmental studies. Unlike a rather uniform design of a mature benchtop FTNIR spectrometer, miniaturized instruments employ diverse technological solutions, which have an impact on their operational characteristics. Continuous progress leads to new instruments appearing on the market. The current focus in analytical NIR spectroscopy is on the evaluation of the devices and associated methods, and to systematic characterization of their performance profiles. Abstract : Small scale : Miniaturized spectrometers have revolutionized near‐infrared spectroscopy by opening up a spectrum of new applications for this already mature analytical technique. This review presents current issues in this thriving field. The diversity of underlying technology, miniaturization versus performance, and very active research areas of systematic feasibility studies aimed at establishing the applicability of these devices are highlighted.
