Revolutionizing optical sensing

IRsweep offers a cutting-edge optical spectrometer in the mid-infrared. Microsecond time resolution combined with large spectral bandwidth and high spectral resolution offers a plethora of new possibilities in molecular analysis.

Real-time observation of enzyme kinetics and chemical reaction monitoring are two out of many application fields of the IRspectrometer.
