Comprehensive Spectroscopy Systems
The HARPIA comprehensive spectroscopy system performs a variety of sophisticated time-resolved spectroscopic measurements in a compact footprint. It offers an intuitive user experience and easy day-to-day maintenance, meeting the needs of today’s scientific applications.
The HARPIA-TA is a transient absorption spectroscopy system. Extension modules and customization options tailor the HARPIA system to specific measurement needs. In particular, it can be expanded using time-correlated single-photon counting and fluorescence upconversion (HARPIA-TF), third beam delivery (HARPIA-TB), and microscopy (HARPIA-MM) modules. HARPIA is designed for easy switching between measurement modes and comes with dedicated data acquisition and analysis software. Each module is contained in a monolithic aluminum body, ensuring excellent optical stability and minimal optical path lengths.
The HARPIA-TG is a novel transient grating spectroscopy system dedicated to the measurement of the diffusion coefficient and carrier lifetime. The fully automated and computer-controlled system enables the measurement in a matter of minutes.

The HARPIA spectroscopy system achieves an excellent signal‑to‑noise ratio at high repetition rate and low energy excitation conditions. The graphs below compare the signal-to-noise ratio (SNR) of difference absorption spectra obtained with a Ti:Sapphire laser operating at 1 kHz and a PHAROS laser operating at 64 kHz with the same acquisition time.
