771 Series Laser Spectrum Analyzer


The most precise wavelength and spectral measurement

The 771 Series Laser Spectrum Analyzer from Bristol Instruments 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 ± 0.2 parts per million, and an optical rejection ratio of more than 40 dB, the model 771 provides the most detailed information about a laser’s spectral properties. 

 

Continuous calibration for reliable 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 at 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 at 1000 nm). These specifications are guaranteed by continuous calibration with a built-in wavelength standard, thereby ensuring the most meaningful experimental results. 

 

Broad wavelength coverage and straightforward operation

The 771 Laser Spectrum Analyzer is available in four broad wavelength configurations to satisfy virtually any experiment requirement. These ranges are the VIS (375 - 1100nm), NIR (520-1700 nm), IR (1-5 μm), and MIR (1-12 μm). The system operates with a PC, running under Windows, via USB or Ethernet. Software is provided to control measurement parameters and to display spectra and to report wavelength data. Or the system can be part of an experiment using a library of commands for custom or LabVIEW programming.
