High Speed Optical Spectrum Analyzer

/ Education systems

IDIL Fibres Optiques has developed a High Speed Optical Spectrum Analyzer with bandwidth 1 GHz dedicated to measure fast physical phenomena in spectroscopy.

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.
