Products & Services

BRISTOL  INSTRUMENTS offers a variety of optical interferometer-based wavelength meters and spectrum analyzers to characterize CW and pulsed lasers that operate from the visible to the mid-IR. These systems measure absolute laser wavelength to an accuracy as high as ±0.0001 nm. In addition to accurately measuring wavelength, the spectrum analyzer systems determine a laser’s spectrum to a resolution as high as 2 GHz. All of the products offered by Bristol Instruments provide the reliable accuracy that will give you greater confidence in your results.

WAVELENGTH METERS

Bristol Instruments’ wavelength meters provide accurate information for scientists and engineers who need to know the exact wavelength of their lasers. These systems use proven Michelson or Fizeau interferometer-based technology to measure absolute wavelength to a guaranteed accuracy as high as ±0.0001 nm. To achieve the reliable accuracy that is expected from Bristol Instruments, all of its wavelength meters include a built-in wavelength standard for continuous calibration. Systems are available for CW and pulsed lasers that operate at wavelengths from 350 nm to 12 µm. They are used for scientific applications at universities, government laboratories, and industry, and for DWDM testing applications at fiber communication component and system manufacturers.

SPECTRUM ANALYZERS

The spectrum analyzers from Bristol Instruments provide the most complete wavelength and spectral characterization of CW and high-repetition rate pulsed lasers that operate from 375 nm to 12 µm. These systems combine proven Michelson interferometer-based technology with fast Fourier transform analysis for accurate measurement of absolute wavelength to ±0.0001 nm and high resolution spectral analysis to 2 GHz. As with all products from Bristol Instruments, every measurement is guaranteed by continuous calibration with a built-in wavelength standard. This ensures the most meaningful experimental results for scientific applications and for the most reliable testing of DWDM signals.
