The HF-8999-780-AUTO from Light Machinery is a Spectrometer that has a narrow band tunable filter to suppress the bright un-shifted laser frequency which operates at a wavelength of 780 nm. This device has a spectral resolution of up to 1.5 pm with a dynamic range greater than 100 dB at 6 GHz. By adjusting the tunable filter, the main laser peak can be suppressed, and the exposure grating can dramatically increase the dynamic range of the instrument. It is available in a 71 x 37 x 15 cm robust unit and is ideal for Brillouin shift Measurements, To measure Hard Materials and even Ultra-Low Frequency Raman spectra, Characterizing Mechanical Properties of Biological Samples, etc.
