Three-dimensional Magnetic Field Probe Station

Dexinmag's one-dimensional, two-dimensional, three-dimensional magnetic field probe station.

 

  1. The coil can be air-cooled (smaller magnetic field) or water-cooled (larger magnetic field), and is equipped with a coil overheat protection device.
  2. It can work stably for a long time when used in conjunction with the high-precision bipolar DC power supply produced by Dexinmag.
  3. The output current in each dimension is controlled by the software or the buttons on the power control panel, and a vector magnetic field in any direction in space can be generated.
  4. The probe station is equipped with a movable sample stage, which can realize two-dimensional movement in the horizontal direction and 360-degree rotation of the sample stage, which is convenient for sample installation and testing.
  5. The probe station has four high-precision probe arms, and is equipped with a high-precision electron microscope, which is convenient for the observation operation of tiny samples.
  6. The probe can be used to test chips, wafers, packaged devices, etc. through DC or low-frequency AC signals.

 

Applications:

 

Widely used in the semiconductor industry, MEMS, superconductivity, electronics, ferroelectronics, physics, materials science and biomedicine and other fields. The three-dimensional probe station is matched with the high-precision bipolar power supply independently developed by Dexinmag. Through the real bipolar power output, the vector field synthesis in any direction in space is realized.

 

Optional accessories:
