Laser Spectrum Analyzer: 771 Series
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 ± 0.0001nm, and an optical rejection ratio of more than 40dB, the model 771 provides the most detailed spectral information for lasers that operate from 375nm to 12μm.
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.
