Electrostatic Levitation

Electrostatic levitation utilizes electrostatic force to suspend charged objects within a controlled electric field, counteracting gravity without physical contact. This containerless processing technique eliminates the need for crucibles, preventing contamination and allowing for the study of materials in ultra-high purity or high-temperature environments.

Matsusada Precision provides high-performance high-voltage amplifiers and power supplies designed for these demanding applications. Our amplifiers feature high slew rates and fast response times, ensuring the precise electric field control necessary to maintain stable levitation.
