Bristol 338 Optical Wavelength Meter

Fast and cost-effective wavelength measurement

Bristol Instruments

 

The 338 Series Optical Wavelength Meter from Bristol Instruments combines speed and affordability to address the most important requirements of optical transceiver manufacturers.

 

The model 338 has a high measurement rate of 25 Hz that results in reduced testing times and greater production throughput. And, its affordable price point, along with a five-year warranty, provides the lowest cost of ownership compared with similar systems.


Features:

  • Fast measurement rate of 25 Hz
  • Wavelength accuracy as high as ± 0.3 pm
  • Automatic calibration with a built-in wavelength standard
  • Measurement confidence level of ≥ 99.7%
  • Traceable to NIST standards
  • Power measured to an accuracy of ± 0.5 dB
  • Convenient touch-screen display reports measurement data in a variety of formats
  • Interfacing via SCPI using USB, Ethernet or GPIB
  • Rugged design for manufacturing environments
  • 5 year warranty

The 338 Optical Wavelength Meter uses proven Michelson interferometer-based technology with fast Fourier transform analysis to accurately measure the wavelength of CW and modulated signals.

 

Two versions are offered. The model 338A is the most precise, providing an accuracy of ± 0.3 pm. For less exacting test requirements, the 338B system is a lower-priced alternative with a wavelength accuracy of ± 1.0 pm.

 

The wavelength accuracy of the 338 Optical Wavelength Meter is maintained over long periods of time because the system is continuously calibrated with a built-in HeNe laser. This is the ideal reference source because its wavelength is well-known and fixed by fundamental atomic structure.

 

To verify the accuracy of the model 338, every system is rigorously tested with laser sources that are traceable to NIST standards.
