Measure the transient absorption spectrum in extremely short time in a high dynamic range with high S/N. 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...

Specifications High dynamic range streak camera C13410-01A The streak camera is an ultra high-speed detector with 5 ps temporal resolution. By combining with the spectrograph, transient absorption spectrums can be measured using with a single shot because multiple wavelengths can be observed simultaneously. The spectrograph is ideally suited for combination with the streak camera. Since an optical system that corrects for astigmatism is used, the light condensing efficiency at the detector is high and high-sensitivity measurements are possible. Streak tube Photocathode Spectral response...
