Development and Application of Near Infrared Spectrometer

摘要

Near infrared (NIR) spectrometer with wavelength range from 900 nm to 1700 nm has been carried out by adopting diode array system, flat-field concave grating and InGaAs linear sensor. This type of NIR spectrometer has many advantages such as simple structure, no moving parts and rapid scanning. The article also introduces the system structure, optical path of grating, circuit architecture, stepless intergrating time, tests and applications about NIR spectrometer. We look forward to providing information for researchers and workers in related industries for reference.
