Wavelength Meters
for Production Testing

Accurate, fast, and cost-effective wavelength measurement


Wavelength meters for testing optical transceivers, WDM transmission systems, and lasers used for LIDAR and 3D sensing.

Our wavelength meters use proven interferometer-based technology to measure laser wavelength to an accuracy as high as ± 0.3 pm. To ensure confidence in your test results, all our wavelength meters include a built-in wavelength standard for automatic calibration.

Bristol Instruments combines speed and affordability to address the most important requirements of manufacturers. Fast wavelength measurement results in reduced testing times and greater production throughput. And, an affordable price point, along with a five-year warranty, provides the lowest cost of ownership.
