An all-inclusive pump-probe/fluorescence upconversion/time-correlated single photon counting spectroscopic system

 

The all-new, all-integrated HERA system combines the best features of HARPIA and CHIMERA spectrometers in a single package. HERA consists of a modified HARPIA framework with an add-on for time-resolved fluorescence measurements. Fundamentally, the HERA system can be viewed as a miniaturized lab covering all the most popular time-resolved spectroscopy experiments. HERA system can provide an extensive comprehension of the intricate photophysical and photochemical properties of the investigated samples. HERA setup unifies multiple time-resolved spectroscopy capabilities, including:

·         - Femtosecond transient absorption

·         - Femtosecond transient reflection

·         - Femtosecond fluorescence upconversion

·         - Hundred picoseconds-to-microsecond time-correlated single photon counting (TCSPC).

·         - Automated measurements of intensity dependence of transient absorption and time-resolved fluorescence

        signals

     Switching between different experimental realizations is fully automated and requires very little user interference. The optical layout of HERA system is refined to offer both an incredibly small footprint (1300×420 mm, see the dimensions below) and an easy and intuitive user experience. Despite its small size, HERA is easily customizable and can be tailored for specific measurement needs.



All the experiments that the HERA system provides are managed by a new and improved user application with experiment-guiding wizards, measurement presets, and development kit for custom applications.


In addition to experiment automation software HERA includes the data analysis package CarpetView for inspecting the acquired data and performing global and target analysis,  probe dispersion compensation, exponential fitting etc. The software package features an intuitive and user-friendly interface; it is delivered with a data analysis tutorial that offers seamless transition from the raw data to publication-quality graphs and model-based parameter estimation. All the software runs under MS Windows and is easy to use. Even a novice will become an analysis expert in a matter of days!
