In high-end precision scenarios such as precise optical path coupling, microscopic imaging posture calibration, optical lens angle leveling, micro-nano device posture correction, and spectral fine testing, traditional electric rotary tables often suffer from problems such as large return gap, low-speed rotation stalling, large angle step size, residual vibration during operation, and poor repeatability. The friction errors and position deviations caused by mechanical gears, worm gears, and bearings in traditional mechanical rotary tables easily lead to optical path angle deviation, imaging distortion, low coupling efficiency, and large experimental data dispersion, failing to meet the strict research needs of ultra-small angle fine adjustment, vibration-free stable rotation control, ultra-high repeatability, and ultra-fast dynamic response. To address the pain points of high-precision angle calibration, Saifan Optoelectronics has launched the piezoelectric rotary table, relying on piezoelectric ceramics drive and an integrated flexible hinge structure, completely breaking through the accuracy bottleneck of traditional mechanical rotary tables and becoming the core preferred equipment for micro-nano angle and precise posture control scenarios.
No mechanical rotation architecture, zero gap and zero jitter in all directions
The piezoelectric rotary table completely abandons the mechanical transmission structures of traditional rotary devices such as gears, worm gears, and bearing friction pairs, adopting a piezoelectric ceramic drive + integrated flexible hinge non-gap transmission process, focusing on precise rotation control of planar angles, eliminating industry-wide problems such as return gap, transmission stalling, low-speed jitter, and mechanical wear from the structural root. The entire machine has no redundant rotating components, the rotation process is smooth and stable, the position is uniform and continuous, and it can achieve ultra-small angle step adjustment that conventional mechanical rotary tables cannot achieve, perfectly adapting to fine posture calibration scenarios such as optical posture leveling, micro-angle correction, precise device rotation position alignment, and subtle angle scanning.
The overall structure is compact and regular, the rigidity is balanced and solid, the force deformation is extremely low, the rotation process has no eccentric shaking, no radial offset, and the angle positioning benchmark is stable and reliable. The body is thin and small, occupying minimal space, not occupying the effective operation space of the experiment, and equipped with standardized universal installation holes, which can be quickly adapted to various optical platforms, microscopic experimental equipment, precision detection fixtures, and multi-dimensional combined positioning systems. It can independently complete single-axis angle fine adjustment, or be combined with translation tables and elevating tables to build a multi-dimensional precise control system, ready for use immediately without complex calibration and debugging, with flexible adaptability in multiple scenarios.
Piezoelectric ultra-fast rotation control, sub-degree-second level accuracy and zero drift
Ultra-micro angle resolution, vibration-free stable rotation, and ultra-high repeatability are the core core advantages of the piezoelectric rotary table.

Whether it is a single precise attitude locking, small reciprocating angle fine adjustment, or long-term high-frequency continuous rotation scanning operations, the angle output is uniform and stable without offset, drift, or accuracy attenuation, firmly holding the ultra-high precision experimental angle calibration bottom line.
The equipment supports open-loop and closed-loop dual-mode precise control, the closed-loop is equipped with a high-precision sensor feedback system, real-time correction and precise locking of all angles, positioning consistency is extremely strong.
