I-MON 512 High Speed

I-MON 512 High Speed USB3 Interrogation monitor (1510-1595 nm)

The I-MON 512 High Speed provides full-spectrum monitoring of FBG sensors at line scan rates up to 17 kHz. The high spectrometer resolution combined with a broad wavelength range provides high-resolution interrogation monitors, enables the measurement of a large number of FBG sensors.

A USB3 interface and a data acquisition software allow plug-and-play operation for integrators of FBG sensing systems.
