In precise optical path coupling, micro-sample attitude correction, optical spot alignment, and microscopic detection calibration, simple planar translation can only achieve point positioning but cannot correct small inclinations or angle deviations, resulting in inaccurate alignment and poor experimental repeatability. The conventional dual-axis translation stage has a single function and has large errors from the combination of split-axis translation and rotation, as well as a cumbersome assembly process, making it difficult to meet the requirements for high-precision two-dimensional attitude fine-tuning. In response to the urgent need for integrated micro-adjustment of planar positioning and angle correction, Sefan Optoelectronics has launched the 7SAA202 electric combined displacement stage, with a dual-dimensional integrated design of translation and rotation, ultra-micro fine travel, and high-precision stable control, specializing in two-dimensional attitude precise calibration scenarios, and becoming a cost-effective preferred model for lightweight and precise experiments.
Integrated planar positioning and angle correction in a single unit for two-dimensional attitude calibration
The 7SAA202 electric combined displacement stage adopts a differentiated modular combination scheme, different from ordinary pure translation dual-axis equipment, innovatively achieving single-axis translation + single-axis rotation two-dimensional linkage adjustment, covering both planar point movement and micro-angle attitude correction, perfectly adapting to various scenarios that do not require three axes but need angle fine-tuning. The equipment is equipped with ultra-small precise travel, with a fine and precise adjustment range, capable of easily completing sample horizontal alignment, optical path angle correction, optical spot posture leveling, and micro-device inclination correction, completely solving the functional shortcomings of traditional dual-axis equipment that can only move but cannot adjust angles.
The entire machine adopts an integrated compact and streamlined structure, with precise assembly and molding, with high shaft system coordination accuracy and excellent coaxiality, fundamentally avoiding gap errors, poor synchronization, and cumulative deviations in split-axis assembly equipment. The body is small and thin, does not occupy experimental space, has a solid structural rigidity, and balances running stability and scene adaptability flexibility. Standardized installation holes are标配， which can be quickly adapted to various small optical platforms， microscopic experimental equipment， and lightweight detection fixtures， ready for immediate use without complex debugging， suitable for multiple lightweight scenarios such as scientific research teaching， precise experiments， and small-scale automation system integration.
Precise micro-control transmission， stable and accurate angle and position in both directions without drift
Point positioning accuracy， fine angle， and high repeatability are the core competitive advantages of 7SAA202. The translation unit of the equipment is equipped with a precise transmission structure and smooth linear guide rails， optimized by professional pre-tightening and gap elimination processes， completely eliminating micro-adjustment problems such as low-speed jitter， transmission jamming， and return gap， with uniform and controllable micro-stepping feed， rapid and sensitive response. The rotation unit supports fine adjustment of extremely small angles， with smooth and unobstructed rotation， capable of precisely correcting micrometer-level and milli-degree-level minor posture deviations. Whether it is single-point precise alignment， small reciprocating translation， or multiple angle correction repetitions， long-term high-frequency fine-tuning operation still maintains stable accuracy without drift， firmly holding the precision standard of precise experiments.
The equipment is equipped with a universal DB9 interface， which can seamlessly match the 7SC series dedicated motion controller， supporting programmatic， automated， and digital precise control， allowing for free setting of translation speed， positioning points， rotation angles， and operation intervals， converting manual manual fine-tuning uncertainty into standardized and replicable precise operation processes. Equipped with photoelectric zero position calibration and dual-end limit protection structures， it effectively avoids overtravel loss， positioning errors， and angle overadjustment problems， ensuring the equipment runs safely and durably. The body is made of high-strength aluminum alloy material， treated with anodizing process， resistant to vibration， deformation， and wear， capable of long-term adaptation to laboratory precise scenarios and mild precision operations， with overall performance stable and reliable.
