New Higher Accuracy 871 Series Laser Wavelength Meter

18 Apr 2017

The newest model of the 871 Laser Wavelength Meter measures the absolute wavelength of pulsed and CW lasers with a reliable accuracy as high as ± 0.2 parts per million, making it the ideal instrument for the most demanding applications.

This instrument uses a unique Fizeau etalon design to generate a spatial interferogram that is detected by a fast photodetector array. Using an on-board digital signal processor, the interferometric data is processed quickly into an accurate wavelength measurement. The combination of these technologies provides an unmatched, sustained measurement rate as high as 1 kHz. The wavelength of every pulse is measured for lasers operating at repetition rates of up to 1 kHz. At higher repetition rates, the system integrates all pulses arriving within a 1 ms window, or an external trigger can capture individual pulses.

Accurate performance is maintained over long periods of time because the system is automatically calibrated with a built-in wavelength standard. The calibration process takes less than two seconds, and can be set to activate at a chosen time interval, or based on the system’s internal thermal conditions.

The 871 Laser Wavelength Meter is available in two broad wavelength configurations to satisfy most experimental requirements. These ranges are the VIS (375 - 1100 nm) and NIR (650 - 1700 nm). A pre-aligned fiber-optic input ensures optimum alignment resulting in uncompromised accuracy. The system operates with a PC running Windows, via a USB or Ethernet interface. Software is provided to control measurement parameters and to report data, or the system can become part of an experiment using a library of commands for custom or LabVIEW programming.
