Introduction of a high-performance active magnetic field canceller created by the micro-vibration measurement technology of patented equipment.
The "AMC-331" is a high-performance active magnetic field canceller that protects electron beam application devices from magnetic field fluctuations. By controlling the disturbance magnetic field detected by magnetic field sensors using a combination of a controller and Helmholtz coils, it suppresses the effects of disturbance magnetic fields. It helps improve the images of electron microscopes and enhances the processing accuracy of electron beam processing devices. 【Features】 ■ Excellent attenuation performance of up to 40-60 dB ■ Achieves about 1/10 the cost compared to magnetic field measures using shielding ■ Simply fix the coils around the device ■ Design coils according to the target device ■ Control multiple disturbance magnetic fields precisely based on frequency analysis *For more details, please refer to the PDF document or feel free to contact us.
