771 Series Laser Spectrum Analyzer

Laser spectral characterization form the visible to the mid-IR


Laser spectral analysis and wavelength measurement with one instrument

The 771 Series Laser Spectrum Analyzer combines proven Michelson interferometer technology with fast Fourier transform analysis resulting in a unique instrument that operates as both a high-resolution spectrum analyzer and a high-accuracy wavelength meter.

With spectral resolution up to 2 GHz, wavelength accuracy as high as ± 0.0001 nm, and an optical rejection ratio of more than 40 dB, the model 771 provides the most detailed information about a laser’s spectral properties.

High wavelength accuracy

Two versions of the 771 Laser Spectrum Analyzer are available. The model 771A is the most precise, measuring wavelength to an accuracy of ± 0.2 parts per million. For experiments that are less exacting, the model 771B is a lower-priced alternative with an accuracy of ± 0.75 parts per million.

These specifications are guaranteed by continuous calibration with a built-in wavelength standard, thereby ensuring the most meaningful experimental results.

Straightforward operation

The 771 Laser Spectrum Analyzer operates with a PC connected directly by USB or through a local area network via Ethernet. Software is provided to control measurement parameters, display spectra, and to report wavelength data. The system can also be integrated directly into an experiment using a library of commands for custom or LabVIEW programming.
