MAGNETIC FIELD SHIELDING

Magnetic Field Cancelling Device

MagEclipse is a system to protect Electron Microscopes and other sensitive equipment such as MRI systems by cancelling out the magnetic field from various sources, affecting performance of these equipment.  Fluctuation in Earth's magnetic field, high-voltage electric transmission lines, cars, trains, electric power stations, elevators, and even vibration of building cause unwanted magnetic field of varying frequencies.  Several other systems are available in the market, but all are much more costly solutions compared to MagEclipse.
     MagEclipse consists of a Control Unit, one or two sensors, and Helmholtz Coils.  It creates a magnetic-field safe space encompassing the sensitive equipment being protected.  It generates opposing magnetic filed, effectively cancelling each other.  It is simple, easy to install, and cost-saving system.  MagEclipse system can be pre-installed in a SEM (scanning electron microscope) or a TEM (transmission electron microscope) if it has an enclosure, so that a SEM or TEM can be insallted without regard to the presence of unwanted magnetic field at the installation site.  Often, a purchaser of an electron microscope needs to find magnetic-field-free installation site or must build a costly shielded room to place the microscope.  MagEclipse can be retrofit easily without physical walls, without need of relocating the microscope during installation, and at far less expense and time.

Pearmalloy

Permalloy has very high magnetic permeability, compared to other materials. Permeability is the degree of magnetization of a material that responds linearly to an applied magnetic field. Permalloy can divert magnetic flux and effectively protect sensitive components from near by magnetic source.

Our Permalloy is extremely thin nickel alloy and is made with special high temperature to produce superior shielding capability against a magnetic field. It is easily made into many forms and shapes by die-press, soldering and cutting.
