771 Series Laser Spectrum Analyzer

The most complete laser spectral characterization from 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 spectral information for lasers that operate from 375 nm to 12 μm.

Guaranteed 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 (± 0.0002 nm @ 1000 nm). For experiments that are less exacting, the model 771B is a lower-priced alternative with an accuracy of ± 0.75 parts per million (± 0.0008 nm @ 1000 nm).

These specifications are guaranteed by continuous calibration with a built-in HeNe laser, 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.

Since the spectral data is generated using an on-board digital signal processor, the 771 Laser Spectrum Analyzer can be integrated into an experiment using a library of commands for custom or LabVIEW programming.
