TimeGate Instruments is a Finnish start-up company founded in 2014. Despite its young age it enjoys strong scientific background. It has commercialized the time resolved Raman spectrometer as a first company in the world. The patented TimeGated® technology is based on pulsed 100 picosecond laser excitation source and time-gated single photon counting array detector. These create a new type of spectrometer able to acquire Raman spectra with real fluorescence rejection.
