I-MON 256 OEM Interrogation monitor (1525 - 1570 nm)

The I-MON 256 OEM Interrogation Monitors offer real-time spectrum monitoring of FBG sensors in the 1550 nm wavelength range at line scan rates up to 35 kHz. A high spectrometer resolution combined with a broad wavelength range provides high-resolution interrogation monitors allowing measurement of a large number of FBG sensors.

A direct interface to the InGaAs detector offers OEM integrators a cost efficient solution for building their FBG sensing systems.

Applications

  • Vibration analysis
  • Temperature measurements
  • Pressure monitoring
  • Strain measurements
