In time-resolved mode, the same gun is driven by an ultrafast laser to create short electron pulses. Attolight’s highly efficient quantitative CL collection system is a crucial component of the Chronos since excitation currents in pulsed mode are up to thousand times less intense than in continuous mode.
Careful synchronization of the excitation laser and the detectors makes time-resolved CL in the picosecond regime a reality. Switching between pulsed and continuous mode is automated and takes a couple of minutes, which makes the system a perfect fit for a multiuser facility where users have multiple demands and throughput is important.
The Chronos is built for researchers who need to access dynamic spectroscopic information with nanometer spatial and picosecond temporal resolutions.
The Chronos features a comprehensive set of ultrafast detectors to cover the UV to IR wavelength range and to optimize performance for your applications. The Chronos’ versatile design also makes it capable of performing advanced methods such as pump/probe spectroscopy and dynamic SEM.
