S51 series is a piezoelectric deflection stage with three-dimensional θx, θy and Z-axis movement, and with a 80×80mm central large aperture. It adopts frictionless flexible hinge structure design, featuring fast response speed and high precision of closed loop positioning. The central large aperture makes it easy to integrate into microscopic and scanning in optical system.

Low-Profile Design S51 piezo stage are specially designed for alignment, nanofocusing, metrology, etc, and features low-profile of only 20mm, easy to integrate into high precision microscopes. |
|
High Guiding Accuracy Resolution
S51 adopts frictionless flexible hinge guiding structure and is optimized by finite element analysis, with high stiffness and guiding precision. |
Frequency and Load Curve 
|
Simulation Analysis Finite element analysis techniques are used to design the highest stiffness in the direction of motion and to reduce angular misalignment. The hinged section allows for extremely high precision movements because the hinge mechanism has no gaps and no friction.
