MAX-QM+ is an automated interferometer for inspection of single and multi-fiber connectors of MTP®/MPO, ST, FC, SC, LC, MU, E2000™, SMA types as well as MT, MT-RJ ferrules.

High measurement speed, portable design, autofocus and a large field of view with the ability to test 12 or 16 fibers per row have made MAX-QM+ an immensely popular solution for high-volume production lines.

MAX-QM+ is supplied with the industry-leading MaxInspect™ software for interferometric inspection of fiber optic connectors.

4.9 sec for MT24,
5.7 sec for MT72.
Measurement Range:
ROC (mm): 1 to flat
Apex offset (μm): 0 to 2000
Fiber height* (μm): more than 1000**
Angles measurements - full range (degrees): 0 to 28***
* Difference from the highest and lowest points of the scanned object.
