671 Series Laser Wavelength Meter

Source: Bristol Instruments, Inc.

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.

The model 671A is the most precise, measuring wavelength to an accuracy of ± 0.2 parts per million (± 0.0001 nm at 500 nm). For experiments that are less exacting, the model 671B is a lower-priced alternative with an accuracy of ± 0.75 parts per million (± 0.001 nm at 1500 nm).

Additional Product Features Include:

  • Wavelength accuracy as high as ± 0.0001 nm
  • Continuous calibration with built-in wavelength standard
  • Operation available from 375 nm to 12 μm
  • Convenient pre-aligned fiber-optic input for wavelengths up to 2.6 μm
  • Free-space aperture input with visible alignment aid for IR and mid-IR wavelengths
  • Straightforward operation with PC using USB or Ethernet
  • Display software provided to control measurement parameters and report wavelength data
  • Automatic data reporting using custom or LabVIEW programming eliminates the need for a dedicated PC
  • Convenient tablet/smartphone application reports measurement data anywhere in the laboratory
  • 5-year warranty covers all parts and labor
