771 Series Laser Spectrum Analyzer

Optical Spectrum Analyzer by Bristol Instruments

Note: Your Quotation Request will be directed to Bristol Instruments.

The 771 Series Laser Spectrum Analyzers from Bristol Instruments operate from 375 nm to 12 µm. These systems combine proven Michelson interferometer-based technology with fast Fourier transform analysis for accurate measurement of absolute wavelength to ± 0.0001 nm and high resolution spectral analysis to 2 GHz and an optical rejection ratio (ORR) of more than 40 dB. Two versions are available - model 771A is the most precise, measuring wavelength to an accuracy of ± 0.2 parts per million (± 0.0002 nm at 1000 nm), model 771B is a lower-priced alternative with an accuracy of ± 0.75 parts per million (± 0.0008 nm at 1000 nm).

They are available in four broad wavelength configurations to satisfy virtually any experimental requirement. These ranges are the VIS (375 - 1100 nm), NIR (520 - 1700 nm), IR (1 - 5 µm), and MIR (1.5 - 12 µm). The system operates with CW lasers, and a special measurement algorithm enables operation with pulsed lasers that have a repetition rate greater than 50 kHz and a pulse length of more than 50 ns.
