The magneto-optical hand-held microscope

Magnetic stray flux can be visualized and evaluated via a mobile „magnetic field sensor“. The mageye, Matesys miniaturized magneto-optical USB magnetic field camera, delivers information about the magnetization of the material in high resolution (µm).


Mobile visualization of magnetic fields

A highly sensitive magneto-optical magnetic field sensor enables a regular USB microscope to see magnetic fields. The mageye is the first real magnetic field camera for high-resolution images of the magnetic stray field on different magnetized samples. A USB interface allows the system to be used in almost every surrounding. Moreover, the integration into a software creates diverse evaluation possibilities.

The mageye was developed for the mobile quality inspection and management, and for the stray field visualization of: magnetic stripe cards, magnetic encoders, welding seams, magnetic audio tapes, manipulated serial numbers, as well as dipole and multipole magnets. Furthermore the system can be applied within the forensics, geology and material development.


Application areas

  • Quality control (e.g. for electrical sheets and of properties of soft magnetic materials
  • Forensics (e.g., recovery of serial numbers on chassis and on weapons)
  • Geology (study of minerals and meteorites)


Technical information & specifications:

• Direct visualization of magnetic fields
• Analysis of polarity, homogeneity, distribution of the magnetic material and the magnetization properties
• Field range 0.01 to 130kA / m (0.1 to 1,600 Oe)
• Sensor size: up to 8x8mm
• USB 2.0 interface
• Portable and easy to use


• Use of the Faraday effect in the magneto-optical sensor
• Internal area lighting using linear polarized light (LED)
• Rotation of the polarization plane of the light in the magneto-optical sensor depending on the locally applied magnetic field
• Analysis of the local changes in intensity with a second polarization filter
• Recording of the magneto-optical image using a high-resolution digital camera (microscope camera)
