The stage is manufactured with materials that meet ultra-high vacuum standards and special processes in IS06 cleanrooms, ensuring that it can be used in ultra-high vacuum environments of 10⁻⁵Pa and below. While realizing high-precision and high-stiffness XY motion, it also ensures the thermal management and magnetic shielding needs in the vacuum environment.
