Fiber optic spectrometer is a new generation of light source and color test instrument. It integrates advanced spectrometer, embedded operating system and microcomputer technology. It is easy to carry, quick, convenient and simple to use, and more in line with parameter test analysis and verification of on-site application scenarios. It can sample and measure light source parameters anytime and anywhere, and can also be connected to PC software test to efficiently analyze and process test data. It has extremely high measurement linearity and accuracy, and is widely used in on-site lighting measurement fields such as homes, shopping malls, schools, factories, greenhouses, outdoors, and various light sources. It can also be used in the research and development of light source products, production line quality monitoring and other links.
