The I-MON OEM Interrogation Monitors are designed for customers who want to make their own electrical interface directly to the diode array. This is ideal for customers who want full control of all electronics and software.

The I-MON 256 OEM and 512 OEM are from our new OEM series using a high speed InGaAs detector array for sensing at 1550 nm. The detectors are pin compatible, which means that electronics operating the 256 OEM can easily be designed to also operate the 512 OEM.

The I-MON 835 OEM offers a cost effective, yet high performing, sensing solution for 835 nm FBG’s.

All our I-MON OEMs are offered with a Developer’s Kit to get started plug and play. You will find more information about the Developer’s Kit in the links above.
