We can also manufacture high-vacuum systems for probing and surface measurements in vacuum. Please feel free to ask us any questions you may have.


  • Positions each of the four probes individually along XYZ axes by using a personal computer and a remote control, while observing the sample surface under an optical microscope.
  • No need to make troublesome sample position adjustments. The sample stage can also be moved independently in X and Y directions.
  • Heating of the samples.
  • Manipulate samples easily and intuitively while observing the sample surface shown on the screen of the personal computer.
