In extreme precision scenarios such as ultra-high vacuum experiments, quantum physics research, semiconductor vacuum coating, vacuum microscopic inspection, and low-dimensional material characterization, conventional electrically-driven stage systems have fatal shortcomings: the mechanical structure requires lubrication with grease, easily emits gas to pollute the chamber, generates micro-dust due to transmission friction, has strong electromagnetic interference, and suffers severe precision degradation. Ordinary precision equipment is completely unable to adapt to the strict conditions of vacuum cleanliness, no magnetic or interference-free, and ultra-high precision. It is highly likely to cause experimental failure, sample contamination, and decreased device yield. To address the urgent need for high-end vacuum environments, nanometer-level precise positioning, no gas emission, no interference, and long-term stable operation, Saifan Optoelectronics has launched a dedicated piezoelectric translation stage for vacuum environments. With no mechanical friction, vacuum-specific design without lubrication, and extreme micro-control performance, it overcomes the positioning challenges in extreme vacuum conditions and becomes the core preferred equipment for cutting-edge research and high-end vacuum manufacturing.
Integrated architecture for vacuum-specific design, no evaporation and no pollution, suitable for extreme chambers
The vacuum-specific piezoelectric translation stage eliminates traditional screw rods, guide rails, and motors in mechanical transmission structures and adopts a one-piece integrated process of piezoelectric ceramics drive and flexible hinges. It is a precision positioning device specially designed for high vacuum and ultra-high vacuum (UHV) conditions. The entire machine has no gears, no screw rods, no rolling friction pairs, and no lubrication at any time. It completely eliminates the industry pain points of oil vapor evaporation, chamber pollution, and residual micro-dust in the vacuum environment. It perfectly meets the strict cleanliness requirements of vacuum experiments. The equipment is selected with special materials and processed through vacuum degassing technology, with an extremely low out-gassing rate. It can stably adapt to ultra-high vacuum environments of 10⁻⁷ mbar or higher and various vacuum chamber closed operation conditions.
The overall structure is compact and regular, without magnetic or interference, and does not generate electromagnetic signal interference during operation. It does not affect the weak optical signals, microscopic samples, and precise electronic devices in the vacuum chamber. It perfectly suits high-sensitivity vacuum research scenarios. The integrated design is rigid and has minimal deformation. No complex assembly and calibration is required, and the axis system has high benchmark accuracy and no deviation. Standardized compatible interfaces are标配， allowing for quick integration of various vacuum chambers， vacuum microscopic systems， and semiconductor vacuum processing equipment. It can be installed and used immediately without cumbersome debugging， and is compatible with various static fine-tuning， dynamic scanning， and vacuum operation modes. The flexibility of scene adaptation is maximized.
Frictionless piezoelectric precise control， zero drift in vacuum全域
Cleanliness without dust， rapid response， ultra-high repeatability accuracy are the core core advantages of the vacuum-specific piezoelectric translation stage. The equipment relies on the mature piezoelectric inverse effect drive principle and an optimized flexible frictionless guiding structure. It has no mechanical jamming， no return gap， no wear and tear， and completely solves the problems of lubrication failure， frictional jamming， and precision drop in traditional displacement equipment in vacuum environments. The positioning resolution can reach nanometer and sub-nanometer levels， and the fine-tuning step distance is controllable. Even in a sealed vacuum environment without interference， it still maintains ultra-precise displacement output， capable of easily completing vacuum precise alignment，全域 scanning， and micro-area characterization in high-precision conditions.
The equipment supports open-loop and closed-loop dual-mode precise control. The closed-loop is equipped with a high-precision sensor feedback system. In the vacuum environment， the positioning is uniform and stable without segment errors or long-term drift.

It can freely set the displacement travel， running speed， and precise positioning points， converting vacuum manual fine-tuning uncertainty into standardized and replicable precision operation processes. The equipment is resistant to high and low temperatures， deformation， and aging， and can be long-term adapted to extreme vacuum conditions. It operates safely and stably， with extremely strong durability.
