Fast and mobile Visualization of magnetic structures and fields

 

magview is a magneto-optical readout device for fast and precise visualization of magnetic field structures. The handheld device can be applied for qualitative testings and stray field analyses. magview visualizes magnetic stray fields of credit cards, magnetic encoders and multipole magnets.

 

 

Visualization of magnetic fields

Magnetic information, such as permanent magnetic structures and inhomogeneities due to fissures and cracks in ferromagnetic materials, can be visualized by use of magneto-optical sensitive sensors. For this purpose the sensor is set in direct contact with the surface containing the magnetic information.

Because of the adaptive design magview is suitable for visualization of low magnetic fields of audio and video tapes, debit and credit cards, floppy disks and hard drives. For digital analyses and data archiving we recommend our cmos-magview.

Functional Principle

  • Integrated homogeneous, linear polarized light illumination (LED))
  • Change of the polarization status of light in the magneto-optical sensor depending on the applied local magnetic field
  • Analysis of local intensity changes via a secondary polarizer
