Brillouin Hyperfine Spectrometer

Brillouin HyperFine Spectrometer


Fast Brillouin Shift Measurements with the HF-8999-PK-LLL

The great challenge with Brillouin spectroscopy is that the Rayleigh light from the pump laser can overwhelm the small Brillouin shi8ed return signal. So, we have combined our leading edge HyperFine spectrometer with a very narrow band tunable filter to suppress the bright un-shi8ed laser frequency. The tunable filter (the Green Killer) is easily adjusted to suppress the main laser peak and exposure gaJng is used by the HyperFine spectrometer to drasJcally increase the full dynamic range of the instrument. This combinaJon achieves a dynamic raJo of 75 db with our ultra low noise sCMOS camera.
