The RSML series is a high‑precision 360° continuous rotary stage powered by a direct‑drive motor with precision ball bearings, delivering excellent dynamic performance and positioning accuracy—with an unloaded crossover frequency exceeding 100 Hz. Featuring outstanding industrial design with a refined and compact form, it offers table diameters of 75 mm, 100 mm, 150 mm, and 200 mm, with a thickness of less than 60 mm. Equipped with high‑precision circular grating feedback, it achieves positioning accuracy better than 6 arcsec, with axial and radial runout below 6 μm—demonstrating outstanding mechanical performance.

Despite its compact construction, the RSML provides robust driving capability, reaching an unloaded maximum speed exceeding 1800 rpm. With linear amplifiers in a vibration‑isolated laboratory environment, it achieves in‑position stability and minimum step size below 1 arcsec. The RSML series features a hollow design with clear aperture options of 6 mm, 15 mm, and 26 mm. Typical applications include metrology inspection, biological sample processing and observation, and film thickness measurement—wherever arcsec‑level positioning is required.
