Optical fiber spectrometer usually uses optical fiber as a signal coupling device to couple the measured light into the spectrometer for spectral analysis. Due to the convenience of optical fiber, users can build a spectrum acquisition system very flexibly. The advantage of optical fiber spectrometer lies in the modularity and flexibility of the measurement system. The miniature optical fiber spectrometer of MUT in Germany has a very fast measuring speed and can be used for on-line analysis. Moreover, due to the low-cost universal detector, the cost of the spectrometer and the cost of the whole measurement system are reduced. The basic structure of optical fiber spectrometer includes grating, slit and detector. The parameters of these components must be specified in detail when purchasing spectrometer. The performance of spectrometer depends on the precise combination and calibration of these components. After calibration, in principle, none of these accessories can be changed.

The optical fiber spectrometer of Pioneer Technology (Hong Kong) Co., Ltd. has become the leader of optical fiber spectrometer with its compact appearance, portable design, convenient operation, high cost performance, electronic system and powerful detector. The spectral measurement range is between 190 nm and 2300 nm, and the wavelength resolution is less than 0. 1nm. The detector adopts plug-in design, which is suitable for various applications and diverse needs of industrial users.
