High Speed Optical Spectrum Analyzer

/ Spectrometer 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.

The spectral detection range covers 366 nm to 844 nm with an optical resolution of 24 nm (customized range and resolution available).
