I-MON series E-USB interrogation monitors offer real-time spectrum monitoring of fiber Bragg grating (FBG) sensors. High spectrometer resolution combined with broad wavelength range provides high-resolution interrogation monitors, allowing measurement of a large number of FBG sensors. High sensitivity also allows high resolution at very low light levels. With its USB interface and data acquisition software,  it provides easy setup with a laptop and can act as a stand-alone monitor in combination with a customer-selected light source.

In addition, the I-MON series E-USB offers straightforward integration with customers' interrogation system control PCB and meet industrial qualification standards.
