The Burleigh WA-1100 is a precision optical wavelength meter engineered for absolute wavelength measurement of CW and modulated laser sources across the near-infrared and visible spectrum. Operating on a scanning Michelson interferometer principle, it compares input laser interference patterns against an internal HeNe reference standard to deliver traceable, calibrated wavelength data. The instrument simultaneously provides optical power measurement, making it suitable for DWDM component characterization, test equipment calibration, and production quality assurance.
