前Flash Photolysis System

The flash photolysis system utilizes dual spectrometers. The front spectrometer of the system splits the light before reaching the sample, effectively attenuating the total intensity of the detection light to prevent sample damage caused by excessive power. The rear spectrometer of the system performs spectral splitting again after the sample, eliminating stray light and ensuring measurement accuracy. With a 500M high-bandwidth oscilloscope, the system’s time resolution is improved. The highly integrated software enables fully automated testing.
