Burleigh WA-7000 Multi-Line Wavemeter

The Burleigh WA-7000 Multi-Line Wavemeter is a precision instrument for simultaneous measurement of multiple laser wavelengths using a scanning Michelson interferometer with Fast Fourier Transform analysis. A HeNe reference laser and advanced digital processing enable high-resolution spectral analysis and real-time wavelength monitoring across the telecom C and L bands. The instrument measures individual peak and total optical power, automatically calculates channel spacing and signal-to-noise ratios, and discriminates up to 200 discrete optical signals with exceptional accuracy.
