The LS series from Magnescale pushes the boundaries of precision measurement—transcending nanometer resolution into the picometer realm. This leap in performance has advanced at a pace reminiscent of Moore’s Law, aligning with Magnescale’s strategy of anticipating and meeting future customer demands. Its exceptional resolution and stability make it indispensable in domains that demand ultimate precision, such as next-generation semiconductor manufacturing, camera-lens mold fabrication, and ultraprecision machining. Furthermore, Magnescale has extended its measurement capabilities beyond one-dimensional positioning to 2D and even 3D, integrating Z-axis sensors and creating some of the world’s most accurate angular encoders.

Magnescale’s LS systems integrate several proprietary technologies to achieve unprecedented accuracy. The grating interferometer scale maintains precision unaffected by temperature fluctuations, air pressure changes, or turbulence. Holographically generated scales produce output signals with exceptional linearity and high diffraction efficiency, ensuring minimal distortion and superior signal-to-noise performance. Additionally, advanced interpolation and signal compensation processing deliver remarkable resolution, with the BS series achieving ~17 picometer resolution using automatic compensation interpolation. LS units are widely applied in ultra-high-precision air-bearing stages, surface roughness and contour measurement systems, DUV wafer inspection systems, non-contact measuring machines, micro-grinding tools, and aspherical surface machining equipment.
