High-Accuracy Laser Wavelength Meter

The 671 Series Laser Wavelength Meter is the best way to measure the absolute wavelength of CW lasers that operate from the visible to the mid-IR. This system provides real-time laser wavelength information with an accuracy as high as ± 0.0001 nm. Continuous calibration with a built-in wavelength standard ensures the reliable accuracy that is needed to generate the most meaningful experimental results.

A proven Michelson interferometer-based design is used to achieve an accuracy of ± 0.2 parts per million (± 0.0001 nm at 1000 nm) with the model 671A. For less demanding experiments, the model 671B is a lower-priced alternative with an accuracy of ± 0.75 parts per million (± 0.0008 nm at 1000 nm). Several broad wavelength configurations are available to satisfy virtually any experimental requirement. These are the VIS (375-1100 nm), NIR (520-1700 nm), IR (1-5 µm), and MIR (1.5-12 µm). For the VIS and NIR versions, optical power is measured simultaneously to provide a more complete analysis of laser performance.
