Bristol 771 Series Laser Spectrum Analyser

Laser spectral analysis and wavelength measurement with one instrument

Bristol Instruments

The 771 Series Laser Spectrum Analyser combines proven Michelson interferometer technology with fast Fourier transform analysis resulting in a unique instrument that operates as both a high-resolution spectrum analyser and a high accuracy wavelength meter. With spectral resolution up to 2GHz, wavelength accuracy as high as ± 0.0001nm, and an optical rejection ratio of more than 40dB, the model 771 provides the most detailed information about a laser's spectral properties.



  • Wavelength measurement and spectral analysis with one instrument
  • Wavelength measured to an accuracy as high as ± 0.0001nm
  • Spectral resolution as high as 2GHz
  • Optical Rejection Ratio of > 40dB
  • Continuous calibration with a built-in wavelength standard
  • Wavelength range options available from 375nm to 12µm
  • Operation with CW and high-repetition rate pulsed lasers
  • Convenient pre-aligned fibre-optic input for visible and near-IR wavelengths
  • Free-space aperture with visible tracer beam for IR and mid-IR wavelengths
  • Sraightforward operation with PC using USB or Ethernet interfaces
  • Windows-based software is provided to control measurement parameters and to display spectra and report wavelength data
  • Integrates into an experiment for automatic wavelength reporting using custom or LabVIEW programming
