Near infrared spectroscopy is being in favor with more and more researchers. As the basis and premise of this technology, the near infrared spectrometer is driving it to develop quickly. In recent years, with the wide application of near infrared spectroscopy, the current near infrared spectrometers are difficult to meet the needs of research and production. Therefore, to improve the performance of near infrared spectrometers, more researchers have done a lot. The research progress of near infrared spectrometers in recent years, such as the progress of hardware, the modification of spectroscopic circuits, the improvement of spectral signal processing and the development of software, is discussed. The development trend of near infrared spectrometers is given.
