Laser wavelength meter uses a Michelson interferometer-based design
The 671 NIR2 laser wavelength meter provides the exact wavelength of continuous-wave lasers that operate from 1.0 to 2.6 μm. It uses a Michelson interferometer-based design to measure laser wavelength to an accuracy of ± 0.0002 nm. It includes a pre-aligned fiber-optic input.
