New Fourier Transform Optical Spectrum Analyzer

Product Announcement from Thorlabs, Inc.

New Fourier Transform Optical Spectrum Analyzer-Image
  Thorlabs' Optical Spectrum Analyzer (OSA) is a general-purpose instrument that measures optical power of the light source as a function of wavelength. This instrument is versatile enough to analyze broadband optical signals, the Fabry-Perot modes of a gain chip, or a long-coherence-length single mode external cavity laser.
