The ASP series is a high‑precision air‑bearing direct‑drive rotary stage powered by a rotary motor, delivering excellent dynamic performance and positioning accuracy. Beyond industry‑leading axial, radial, and tilt error motion, it offers exceptional absolute angular accuracy, repeatability, and load capacity—easy to integrate into multi‑axis systems. Featuring outstanding industrial design, the ASP is available with table diameters of 100 mm and 150 mm, with other sizes customizable upon request. Equipped with high‑precision circular grating feedback, it achieves positioning accuracy better than ±1.5 arcsec, with axial and radial runout below 250 nm, demonstrating outstanding mechanical performance.

Powered by CoreTech’s proprietary direct‑drive motor with high torque and strong driving capability, the ASP achieves an unloaded speed exceeding 5000 rpm. With linear amplifiers in a vibration‑isolated laboratory environment, it achieves in‑position stability and minimum step size below 0.5 arcsec. Typical applications include dimensional metrology, wafer spiral inspection, biological sample processing and observation, synchrotron research, precision manufacturing, optical alignment, and system calibration—wherever arcsec‑level positioning is required.
