This ASD proprietary software and hardware diagnostic tool was developed so that people using ASD spectrometers can check the internal glass fibers built into the fiber optics.

The Fiber Checker allows the user to reverse illuminate the VNIR, SWIR 1 and SWIR 2 regions individually or all together.

By attaching the Optical Magnifier and counting the illuminated fibers, the user can then confirm that there are no broken fibers internally on the fiber optic cable.
