Stacked Three-axis Linear Displacement Table

  • 格物光学-堆叠式三维直线位移台.png



    The Lattice Optics L3S190-350 series stacked 3D linear displacement table adopts modular, ultra-thin design, orthogonal design and other concepts. The MZM200-10 standard module is integrated on the cross platform L2S125 module, which can achieve high-precision and high stiffness linear motion in X, Y and Z axes with 3 degrees of freedom. Among them, the MZM200-10 standard module adopts large stroke maglev gravity compensation technology, which has the function of reducing the load on the vertical motor, greatly improving the vertical motion performance and service life, and achieving high-precision vertical positioning for lifting and lowering. The L2S125 module of the cross platform adopts an integrated and orthogonal design concept, with a compact and flat contour size, which can achieve high-precision and high stiffness linear motion with 2 degrees of freedom in the horizontal X/Y axis. It can be widely used in wafer production control applications, such as thin film measurement, critical dimension inspection, as well as wafer marking and wafer laser annealing.
