High-Speed Optical Wavelength Meter: 828 Series

The 828 Series High-Speed Optical Wavelength Meter uses interferometer technology that is very different than that employed by other wavelength meters used for WDM wavelength testing applications. A Fizeau etalon design is used to generate a spatial interferogram that is detected by a fast InGaAs 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 of 1 kHz.  

Features Include: 

  • Wavelength measured to an accuracy as high as ± 0.3 pm
  • Measurement rate of 1 kHz for reduced testing times  
  • Automatic calibration with a built-in wavelength standard
  • Measurement confidence level of ≥ 99.7% 
  • Traceable to NIST standards
  • Simultaneous measurement of optical power to ± 0.5 dB
  • High sensitivity of -40 dBm (0.1 µW)
  • Operates with CW and modulated signals
  • Rugged design for manufacturing environments
