Paper Abstract

A novel micro-ultraviolet spectrometer system with characteristics of small size, low price and high performance was developed and the main performance parameters were tested. The wavelength range is 190-410nm, the wavelength accuracy is less than 1nm, and the resolution is less than 3nm (using 100um fiber). To verify the system performance, a pollution-free water quality testing platform was built based on the micro-ultraviolet spectrometer and experiments of chemical oxygen demand (COD) testing were made. The results indicated that the system performance can meet the practical demands of real-time water quality monitoring.
