It spectrally analyze the optical spectrum of an incident light beam through a diffraction grating. This system includes two sub-assemblies:
● an optical bench splits spectrally the incident beam and injects in 20 independent fibers arranged in a line at the output grating.
● an opto-electrical board composed by 20 avalanches photodiodes with power supply and amplification.
