Magneto-Optical Visualization
The cmos-magview is a digital magneto-optical system for the fast and accurate visualization of magnetic stray field structures. The sensor system allows real-time stray field analyses and quality testing of magnetic materials. Magnetic stray fields of, for instance, magnetic stripe cards, magnetic encoders and di- and multi-pole magnets can be visualized. A comprehensive user Software illustrates the images in false color.
Detail Specification
Visualization
The cmos-magview can visualize the distribution and geometric orientation of the magnetic flux density and its changes in high resolution. Inhomogeneities and cracks in ferromagnetic materials can be detected directly using sensitive magneto-optical sensors. For a measurement the sensor is applied directly to the surface containing the magnetic information. The cmosmagview software allows real-time analyses and documentation of magnetic properties
