The CW wavelength meters from Bristol Instruments are ideal for scientists and engineers who need to know the exact wavelength of their CW laser. The 671 and 238 systems employ a proven Michelson interferometer-based design to measure laser wavelength extremely accurately. What’s more, this is accomplished with an unprecedented level of reliability, versatility, and convenience.
The most important aspect of a laser wavelength meter is its accuracy. Bristol Instruments guarantees this specification by taking into account all factors that can affect wavelength measurement. Wavelength accuracy is quantified by Bristol Instruments using the NIST definition for expanded uncertainty. Components of error arising from both systematic and random effects are included. Systematic errors result in an offset between the measured value and the true value. Random errors result in measurements that have a statistical distribution associated with short-term measurement repeatability. Our CW wavelength meters are designed to address both types of uncertainty. Continuous calibration with a built-in wavelength standard corrects for potential sources of systematic error. Random errors are minimised with a robust Michelson interferometer design.

|---|---|---|
 | The 238 Series Optical Wavelength Meter from Bristol Instruments is designed for the precise wavelength characterisation of tunable transmitter lasers, DFB lasers, and VCSELs used in applications such as fibre optic communications, data storage, and 3D sensing. | |
 | The 338 Series Optical Wavelength Meter from Bristol Instruments combines speed and affordability to address the most important requirements of optical transceiver manufacturers. A high measurement rate of 25 Hz results in reduced testing times and greater production throughput, and the affordable price point, along with a five-year warranty, provides the lowest cost of ownership compared with similar systems. | |
 | The 438 Series Multi-Wavelength Meter from Bristol Instruments combines proven Michelson interferometer-based technology with fast Fourier transform analysis to measure the wavelength, power, and OSNR of as many as 1000 discrete optical signals. | |
 | The 671 Series Laser Wavelength Meter uses proven Michelson interferometer-based technology to accurately measure the wavelength of CW lasers that operate from 375 nm to 12 μm. Two versions are available. | |
 | The 828 Series Optical Wavelength Meter from Bristol Instruments is designed to revolutionise the production of tunable transmitter lasers used in WDM applications. |
These CW wavelength meters are part of the Bristol Instruments range offered by Laser 2000.
Bristol Instruments was founded in 2005 by three technical and marketing leaders of the now-defunct Burleigh Instruments. Together, this group has over 80 years of combined experience in the design, manufacture, and marketing of lasers and precision test instruments used in basic and applied research, engineering, and production test applications.
For over 30 years, Laser 2000 has supplied fibre optic equipment and worked with global partners like VIAVI Solutions, US Conec and INNO Instrument.
