Fast visualization of magnetic structures


Being a small and light testing device, minimo can be used as a stationary and mobile system for fast visualization of magnetic stray fields.



The webcam-based minimo is applicable for a qualitative examination of magnetic stripe cards, removed serial numbers and hard magnetic material structures.   In addition to plug-and-play ability and image archiving a simple change of the magneto-optical sensor head is possible. minimo can be equipped with all types of magneto-optical sensors. This allows an adaption of the Minimo to the sample field strength. A high mechanical stability for mobile use is provided by the robust metal housing.


  • The device is an optimal addition to the magview family
