Visualization of Magnetic Fields and Structures

With cmos-magview Magnetic Field Camera devices, magnetic stray fields and structures can be precisely visualized and measured in seconds.

Product Description

The devices of the cmos-magview Magnetic Field Camera family are high-resolution and precise measuring and visualization systems for magnetic materials, assemblies and surfaces. Pole distances or other geometric information can be measured down to the µm range.

The devices use the Faraday effect in the magneto-optical sensor. Depending on the configuration and calibration of the devices, it is also possible to measure the magnetic field strength perpendicular to the sensor surface. Depending on the application, we offer the devices with different magneto-optical sensors and sensor sizes. The systems are available in the versions cmos-magview S, cmos-magview M, cmos-magview L and cmos-magview XL.

Design & Function

Magnetic fields are used in a wide variety of applications. They help to transmit forces and torques, control sensors and carry information about the state of magnetizable components.

With the cmos-magview, the magnetic field can be visualized two-dimensionally in the highest possible resolution and the magnetic field strength can be measured. All you have to do is place the sample to be examined on the sensor and you will obtain a magnetic field image. Due to its high sensitivity and resolution, the method visualizes pole structures, material inhomogeneities, magnetic domains, grain structures as well as cracks. The cmos-magview is used, for example, in quality and incoming goods inspection.

It is part of the basic equipment of laboratories and supports the development, analysis and function optimization of magnetic systems. Comprehensive and adaptable software provides the user with a solid basis to perform a wide range of analyses and measurements.

The cmos-magview Magnetic Field Camera provides analyses for:

magnetized and partially magnetized permanent magnets
magnetic encoders electrical sheets,
structural changes in steel and stainless steel due to heat treatment or deformation
the testing of magnetic safety features
the inspection of serial numbers in chassis or on weapons

Equipped with type D sensors, the instruments can even visualize soft magnetic structures using various excitation methods.
