In the nanoscale alignment of semiconductor lithography, in the precise assembly of optical lenses, and in the three-dimensional scanning of biological samples, "precise displacement" has long been the key factor determining the success of experiments and product yield. The errors of traditional manual displacement tables and the insufficient rigidity of ordinary electric tables have become invisible barriers in the field of precision. Since 22 years of deep research in precise motion control, Saifan Optoelectronics has匠心crafted a series of three-dimensional electric displacement tables， redefining the standard of three-dimensional positioning with "sub-micron accuracy + full closed-loop control + extremely strong adaptability"， unlocking "displacement freedom" for scientific research and industrial scenarios.
Sub-micron accuracy， no place to hide errors
Precision is the soul of the displacement table. Saifan's three-dimensional electric displacement table adopts cross roller guide rails + pre-tightening gap elimination structure， combined with high-precision optical gratings for full closed-loop feedback， with a resolution of up to 0.01μm， a repeatability positioning accuracy of ≤±0.1μm， and an absolute positioning accuracy of ±0.5μm (customized models can reach ±0.05μm). When the X/Y/Z three axes are linked， through algorithm compensation for mechanical gaps and thermal deformation， errors that "affect the whole due to a single action" can be avoided， achieving seamless switching from macro positioning to micro calibration. Whether it is mask alignment in wafer lithography or sub-micron alignment in fiber coupling， it can precisely reach the target position， ensuring that every displacement is accurate to the millimeter.
Combining rigidity and flexibility， stable and efficient
Breaking the stereotype of "high precision requires low speed"， Saifan displacement tables achieve comprehensive performance balance. Equipped with high-performance stepper/伺服 motors， the maximum speed in no-load is up to 1000mm/s， and the acceleration is 5g， meeting the high-speed positioning requirements of semiconductor packaging and laser processing. The high-strength aluminum alloy frame + reinforced rib design can support a maximum load of 200kg， even when equipped with heavy optical components， the table surface can still maintain a stability of ≤0.5μm. The XY axis is equipped with stainless steel dust-proof covers， and the Z axis uses accordion cloth protection， combined with an intelligent cooling system， it can operate stably in laboratory clean environments and industrial sites， with vibration amplitude ≤0.5μm， avoiding damage to precision samples.
Intelligent adaptation， seamless integration in all scenarios
With modular design to adapt to diverse needs， Saifan's three-dimensional electric displacement tables provide flexible options： travel ranges cover 10mm-4000mm， table surface sizes range from desktop level to industrial level 600×600mm， and support customization for regular， vacuum， and low-temperature environments. Standard equipped with USB， RS232， EtherCAT communication interfaces， compatible with LabVIEW， Python programming environments， can seamlessly integrate into automation systems， supporting point storage， linear interpolation and other complex trajectory planning， without the need for coding skills， users can quickly get started. The center through-hole and multi-hole position design is convenient for cable and optical path wiring， suitable for optical detection， multi-position scanning and other complex layouts.
Empowering thousands of industries， domestic benchmark strength
With outstanding performance， this series has been widely used in semiconductor， optics， and biomedicine fields： safeguarding "China's chips" yield in wafer inspection， achieving high-precision pattern formation in laser engraving， accelerating new drug research in pathological section scanning. As a pioneer of domestic substitution， Saifan displacement tables have passed ISO9001 certification， core components have a 3-year warranty， and the full life cycle cost is 40% lower than imported brands， with continuous improvement in penetration rates in the Chinese Academy of Sciences system and national major projects.
From the frontier exploration in the laboratory to the large-scale manufacturing on the production line， Saifan Optoelectronics' three-dimensional electric displacement tables with precise， stable and efficient performance have become the core engine of precision manufacturing. Choosing Sevan means choosing a "reliable, hassle-free, and scalable" long-term partner. With Sevan, every three-dimensional displacement can precisely empower innovative breakthroughs, driving domestic precision equipment to reach higher levels!
