The Piezoelectric Screw Actuator PTP09D provided by LBTEK features a compact design and can be directly integrated into precision translation stages or optical mounts, enabling long-travel, nanometer-level linear or rotational Motion Control. The actuator supports a maximum axial load of 30 N, with a typical step size of 10-30 nm, and features a power-off self-locking function. With the matching piezoelectric Motion Controller and Software, the single-step size can be flexibly adjusted within ±20% of the reference value of approximately 10 nm. However, due to the open-loop driving principle, piezoelectric hysteresis effects, and actual operating conditions, the actual output step size of the system may fluctuate within a certain range and typically does not offer strict step repeatability. Additionally, LBTEK provides separate 1-inch and 2-inch mirror mounts for compatibility.
