Time-Resolved Absorption Spectrum Analysis System

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, timeresolved absorption spectra and transient absorption time-resolved spectral images can be measured simultaneously, and you can obtain images of irreversible phenomenon. The newly developed C7700-01 high dynamic range streak camera is employed as the detector. Minute transient absorption changes can also be measured in a high dynamic range with high S/N.

FEATURES
･  Measurements  with  the  smallest  optical  density(OD)  of  0.005  (for  single  shot,  OD  value  is  0.02  or  less)
･  Simultaneous  measurements  of  multiple  wavelengths  using  a  single  shot
･  High  time  resolution
･  Automatic  measurements  with  computer  control

  The  time-resolved  absorption  spectrum  analyzing  system  is  conposed  of  a  pump  and  probe  lights,  optics  including  shutters  (a  streak  camera  transient  absorption  measurement  optical  system)  a  detector  part  (a  spectroscope,  a  high  dynamic  range  streak  camera,  and  high  sensitive  digital  camera),  delay  generators,  and  a  data  analyzer.  For  example,  a  high-output  Xenon  lamp  amd  a  nano-second  QSW  YAG  laser  are  utilized  as  the  pump  and  probe  lights  respectively.  The  pump  and  probe  lights  are  operated  the  shutters  on  the  transient  absorption  measurement  software  in  the  data  analyzer,  and  time  resolved  images  such  as  Data  Monitor,  (Emission)  and  Dark  images  are  measured  by  the  detector  part.  Transient  absorption  image  is  obtained  from  the  time-resolved  images  by  calculation  with  analysis  functions.
