About This Product
Nanosecond transient absorption spectroscopy system using electrical delay of pump light and probe light. EOS is a revolutionary system that enables transient absorption measurements in the sub-nanosecond to sub-millisecond range using a pump-probe method that uses electrical delays.
When studying photoinduced processes using ultrafast spectroscopy, it is often desirable to perform measurements over a wide time range. EOS solves this problem by using sub-nanosecond pulsed white light as the probe light using a cutting-edge photonic crystal fiber, achieving a time resolution of less than 1 ns and extending the measurement time width to the sub-second range. made possible. Furthermore, by combining it with the femtosecond pump-probe transient absorption system HELIOS, it is possible to perform continuous transient absorption measurements over the entire time domain. Moreover, the optical system is housed in a compact housing, and switching of detectors is performed automatically, so there is no need for troublesome daily adjustments. EOS is a state-of-the-art nanosecond transient absorption spectroscopy system that incorporates a wealth of cutting-edge technology and is extremely easy to use.
