Jingyi Optoelectronics' fluorescence measurement system includes an excitation light source, a measurement bracket and optical fiber, a receiving spectrometer, fluorescence measurement software, etc. This system is suitable for fluorescence measurement of solids and liquids. Different samples generally have different excitation light sources. Jingyi Optoelectronics offers high-efficiency excitation light sources such as lasers, LEDs, and xenon lamps to choose from, which can also be customized according to specific needs. Since the energy of fluorescence is relatively weak, this system employs a high-sensitivity spectrometer, and the wavelength range of the spectrometer can be customized based on user requirements.
