• 详细介绍

  Transient absorption spectrometers use "pump" pulses to excite molecular systems, and then use probe pulses to obtain system information to study molecular properties after a delay.

  Our transient absorption spectrometer can adapt to the widest range of transient absorption measurement. It has a variety of modular designs to allow the selection of "pump" and "detection" pulses and the easy interchange of transmission and reflection modes of operation. Standalone and Lab ViewTM are compact in design, occupying a small amount of precious desktop space, with good stability and automatic operation. The pump source is compact, seamless coverage, and wide tuning.
