Laser Wavelength Meters and Spectrum Analysers

Laser Wavelength Meters and Spectrum Analysers

Laser spectral analysis for laser R&D and telecommunication applications.

Supplier: Bristol Instruments

Bristol Instruments

Technology type: Spectrometers

Bristol Instruments offers laser wavelength meters and spectrum analysers for laser R&D and telecommunication applications.

Their portfolio covers three core technologies: laser wavelength meters, laser spectrum analysers, and single and multi-wavelength meters (telecommunications industry only). These solutions provide unmatched accuracy of +/- 0.0001nm.

Range features

A high level overview of what this range offers

  • Best wavelength meters for researchers and engineers who need to know the exact wavelength of their lasers
    - Bristol Instruments’ wavelength meters models 671 and 871 use proven interferometer-based technology to measure absolute wavelength to accuracy as high as ± 0.0001nm for CW and pulsed lasers that operate at wavelengths from 375nm to 12µm
  • Some of the Bristol Instruments’ wavelength meters are dedicated to the telecommunications industry
    - Series 238, 338, 428, and 828 will allow precise wavelength and side-mode suppression ratio measurement on telecommunication laser systems from 700nm to 1650nm
  • Spectral analysis and wavelength measurement in one instrument
    - Bristol Instruments’ laser spectrum analysers (771 and 772) combine proven Michelson interferometer technology with fast Fourier transform analysis to operate as both a high-resolution spectrum analyser and a high-accuracy wavelength meter for pulsed and CW lasers from 375nm to 12μm
