The 772B-MIR Laser Spectrum Analyzer combines proven Michelson interferometer technology with fast Fourier transform analysis to characterize the spectral properties of CW and pulsed lasers that operate from 1 to 12 μm.

What makes the 772B-MIR system unique is that it employs a sophisticated algorithm to enable the measurement of pulsed lasers that have a repetition rate as low as 50 Hz.

The 871 Laser Wavelength Meter uses a proven Fizeau etalon design to measure the wavelength of pulsed and CW lasers to an accuracy as high as ± 0.2 parts per million (± 0.0002 nm at 1000 nm). Automatic calibration with a built-in wavelength standard guarantees this performance to ensure the most meaningful experimental results.

The 871 Laser Wavelength Meter generates a spatial interferogram that is detected by a fast photodetector array. An on-board digital signal processor quickly converts the interferometric information to wavelength. Because this calculation is done internally, a sustained measurement rate as high as 1 kHz is achieved.

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 information about a laser’s spectral properties.
