The time-resolved absorption spectrum analysis system is a device to perform transient absorption spectrum measurements in extremely short time. This system enables to analyze the formation and decay process of a reactive intermediate in a photoreaction in solutions, solids, membranes, etc are possible. By using the streak camera as the detector and performing multiple-wavelengths time-resolved measurements with a single shot, time-resolved absorption spectra and transient absorption time-resolved spectral images can be measured simultaneously, and you can obtain images of irreversible phenomenon. The newly developed High dynamic range streak camera C13410 is employed as the detector. Minute transient absorption changes can also be measured in a high dynamic range with high S/N. 《Picosecond system》Time resolution: 90 ps, Measurement time range: 0.5 ns to 20 ns.
