In precise optical path coupling, microscopic imaging leveling, wafer orientation correction, and micro-device detection in various sophisticated scientific research scenarios, simple translational fine-tuning can only correct positional deviations but cannot solve the problems of plane inclination and bidirectional angle offsets. Conventional single-rotary-axis equipment has limited adjustment dimensions, and the split dual-rotor module assembly has large gaps, poor synchronization, and low repeatability, making it difficult to meet the requirements of high-precision two-dimensional orientation calibration. To address the needs of two-dimensional angle fine-tuning, full-plane attitude correction, and ultra-high repeatability positioning, Saifan Optoelectronics has launched the 7SAA201 electric combined displacement stage, featuring a dual-axis electric rotation integrated architecture, ultra-stable precise micro-control, and compact integrated design. It specializes in two-dimensional multi-angle fine calibration conditions and is a cost-effective preferred model for lightweight precision experiments and equipment integration.
Dual-axis rotation integrated architecture, full-plane attitude calibration
The 7SAA201 electric combined displacement stage adopts an industry-scarce dual-axis rotation modular combination scheme, different from translational + rotation, single-axis rotation and other conventional models. It is a completely new realization of dual-axis electric linkage angle adjustment, capable of completing precise two-way angle fine correction for plane pitch and yaw, covering all aspects of two-dimensional plane subtle attitude deviation correction requirements, and perfectly adapting to scenarios that do not require linear translation but only high-precision angle leveling and alignment. The angle adjustment range of the equipment is finely controllable, with extremely small fine-tuning step size, capable of precisely correcting milli-degree-level subtle inclination angles, completely solving the pain points of traditional fine-tuning equipment with single-angle dimensions, rough calibration accuracy, and incomplete attitude correction.
The entire machine adopts an integrated compact and streamlined structure, with multiple processes of precise assembly molding. The shaft system is closely matched and has excellent coaxiality. It fundamentally avoids gap errors, asynchronous operation, and cumulative deviations caused by the assembly of split modules. The body is thin and compact, with extremely low space occupation, a solid structural rigidity, excellent anti-deformation and anti-vibration performance, and a balance of running stability and scene adaptability flexibility. It is equipped with standardized universal installation holes, which can be quickly adapted to various small optical platforms, microscopic experimental equipment, and precision inspection fixtures, ready for immediate use without complex debugging, and widely adaptable to multiple lightweight scenarios such as scientific research teaching precision experiments, optical precision debugging, and small automation system integration.
Precise control and transmission, zero drift and high repeatability in high-frequency calibration
The accuracy, synchronization, and high repeatability of the 7SAA201 are its core core advantages. The dual-rotation unit of the equipment is equipped with a precise transmission structure, optimized through professional pre-tightening and gap elimination processes, completely eliminating common calibration problems such as rotation jamming, return gap, and low-speed jitter. The rotation process is smooth and uniform, with rapid and sensitive response. The two axes are independently controllable yet can be synchronized and linked. It can complete precise single-directional correction and also achieve bidirectional coordinated attitude leveling. Whether for single-time fine adjustment or long-term high-frequency reciprocating calibration, it always maintains constant high-precision output without deviation or angle drift, firmly holding the precision bottom line of precise experiments.
The equipment is equipped with a standard DB9 interface, which can seamlessly match the 7SC series dedicated motion controller, supporting programmatic, automated, and digital precise control. It can freely set the rotation angle, running speed, and adjustment range, converting the uncertainty of traditional manual manual fine-tuning into standardized, replicable, and batch-reusable precise operation processes. It is equipped with an optical zero position calibration and double-end limit protection structure, effectively avoiding over-travel loss, angle over-tuning, and positioning errors. It provides comprehensive protection for equipment operation safety and stability. The body is made of high-strength aluminum alloy material, treated with anodizing process, wear-resistant, durable, and resistant to interference. It can be long-term adapted to laboratory precision conditions and mild precision industrial operations, with overall stable and durable performance.
