7-FRSpec
Used to measure fluorescence intensity
The performance of our fluorescence measurement system is typically assessed using the signal-to-noise ratio of pure water Raman. When tested using modulation methods, the Raman spectra of pure water are displayed as follows. Equipped with specialized fluorescence testing software, our system can measure excitation spectra, emission spectra, and synchronous spectra with precision and ease.
