WaveCapture FBG Analyzer-IRS

Integrated Spectral Analyzer with an Internal Reference Source for Ultra Precise FBG Sensor Measurements

Advanced Energy's WaveCapture Fiber Bragg Grating Analyzer (FBGA) spectral analyzer with an internal reference source (IRS) serves as the heart of precise, fast, and reliable FBG sensing systems requiring increased precision. The addition of the IRS enables greater repeatability for FBG sensing systems or research requiring repeatability better than 2 pm.

  • Ultra-reliable spectral analyzer grating with no moving parts
  • Excellent wavelength repeatability and resolution
  • Ultra-fast response time (up to 5000 Hz)
  • USB 2.0 interface
