The Bravo spectrometer uses a patented technology called SSE™ (Sequentially Shifted Excitation, patent number US8570507B1) to mitigate fluorescence. The device has two excitation lasers (DuoLaserTM, 785 nm, and 852 nm) that can be temperature-shifted three times over a small wavelength range (about 0.4 nm). Both laser beams impinge on the sample sequentially in every measurement, covering a broad spectral range from 170–2000 cm−1 and 2000–3200 cm−1, exploiting the 852 nm and 785 nm lasers, respectively. The laser power was set automatically, reaching a maximum of 100 mW for an 852 nm laser, in an area spot of about 100 μm × 500 μm.
