871 Series Fast Laser Wavelength Meter

20 Jan 2021

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. 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.

Wavelength measurements can be reported at this rate by data streaming with an RS-422 serial interface, or an internal data buffer is available to save up to one million measurements.

A laser under test enters the 871 Laser Wavelength Meter through a pre-aligned fiber-optic input connector. This ensures optimum alignment of the laser beam to the system’s Fizeau etalons resulting in uncompromised accuracy.

The 871 Laser Wavelength Meter operates with a PC connected directly by USB or through a local area network via Ethernet. Software is provided to control measurement parameters and to report wavelength data, or the system can be integrated directly into an experiment using a library of commands for custom or LabVIEW programming. In addition, a browser-based application can be used with a tablet or smartphone to display laser wavelength information anywhere in the laboratory.
