Bristol 771 Series Laser Spectrum Analyser

The 771 Series Laser Spectrum Analyser combines proven Michelson interferometer technology with fast Fourier transform analysis resulting in a unique instrument that operates as both a high-resolution spectrum analyser and a high accuracy wavelength meter. With spectral resolution up to 2GHz, wavelength accuracy as high as ± 0.0001nm, and an optical rejection ratio of more than 40dB, the model 771 provides the most detailed information about a laser's spectral properties.

The new 771 NIR2 adds a detection range of 1 - 2.6 µm, with the convenience and consistent performance of a pre-aligned fibre-optic input coupling.

Features:

• Wavelength measurement and spectral analysis with one instrument

• Wavelength measured to an accuracy as high as ± 0.0001nm

• Spectral resolution as high as 2GHz

• Optical Rejection Ratio of > 40dB

• Continuous calibration with a built-in wavelength standard
