In the nanoscale lithography of semiconductor wafers, a 0.1-micron positioning deviation can lead to the scrapping of the entire wafer; in the assembly of multiple optical lenses, an error of sub-micron level in tilt will significantly reduce the imaging clarity; in the automatic scanning of biological samples, a slow displacement speed will slow down the cycle of new drug research and development...
For research and industrial scenarios that pursue "extreme precision", "displacement" is no longer just a simple "movement", but a "core variable" that determines success or failure. The "handshake error" of traditional manual displacement tables, the "response lag" of semi-automatic platforms, and the "insufficient rigidity" of ordinary electric tables have become "invisible shackles" that restrict precise manufacturing and scientific exploration.
Safan Optoelectronics has been deeply engaged in precise motion control for 22 years, with the mission of "making every displacement precise and controllable". It has launched a full range of electric displacement tables - using "micron-level accuracy + intelligent control + super stability" to unlock "displacement freedom" for precise manufacturing and scientific experiments.
Safan Electric Displacement Table: The Three Core Aspects of "Defining Precise Movement"
In the precise field where "a difference of a hair's breadth can lead to a thousand-mile error", Safan Optoelectronics' electric displacement table, with its "precision, speed, and intelligence" threefold technical barrier, has become the "preferred coordinate" of industry customers.
1. Precision: A leap from "millimeter-level" to "sub-micron-level", making errors nowhere to hide
The soul of the displacement table is "accuracy". Safan electric displacement tables adopt cross roller guide rails + pre-tightening gap elimination structure, combined with high-precision optical encoders (resolution up to 0.01 μm) and closed-loop servo control systems, achieving repeat positioning accuracy of ±0.1 μm and absolute positioning accuracy of ±0.5 μm (some models up to ±0.05 μm), far exceeding industry standards.
Nano-level fine-tuning capability: Supports "coarse adjustment + fine adjustment" dual mode switching, with rapid coarse positioning (speed up to 500 mm/s), fine adjustment step accuracy of 0.001 μm, meeting the needs of all scenarios from macro assembly to micro calibration;
Multi-axis linkage zero coupling: When X/Y/Z three axes or multiple axes are linked, through algorithm compensation for mechanical gaps and thermal deformation, ensuring the "independence" of multi-degree-of-freedom motion, avoiding "cumulative errors caused by a single action affecting the whole".
2. Speed and load: Combining rigidity and flexibility, suitable for "fast-paced" and "heavy tasks"
Precision does not mean "slow motion". Safan electric displacement tables break the stereotype that "high precision requires low speed":
High-speed response: Equipped with high-performance stepper/servo motors (optional linear motors), the fastest speed in no-load is up to 1000 mm/s, acceleration of 5g, meeting the strict requirements of "instant positioning" in semiconductor packaging, laser processing, etc.;
Load-free worry: High-strength aluminum alloy frame + reinforcement design, maximum load capacity up to 200 kg (customized models can be higher), even when carrying heavy optical components or precision fixtures, still maintaining stable displacement;
Low vibration characteristics: Optimizing the structure design through finite element analysis, the vibration amplitude during operation is less than 0.5 μm, avoiding damage to precision samples (such as biological slices, thin film devices) due to vibration.
3. Intelligent control: Evolution from "single machine operation" to "system integration"
Safan electric displacement tables are not only "execution terminals", but also "intelligent nodes":
Open control system: Supports various communication protocols such as USB, RS232, EtherCAT, and is compatible with mainstream programming environments such as LabVIEW, Python, etc., enabling seamless integration with customers' existing automation systems;
One-click programming and trajectory planning: Has a graphical user interface, supports presetting of complex trajectories such as point storage, linear interpolation, and circular interpolation, allowing researchers without coding skills to complete the automated testing process; Real-time status monitoring: Provides real-time feedback on parameters such as displacement, load, and temperature. Automatically alarms and stops the machine in case of abnormalities. Combined with remote diagnosis function, it enables "zero-distance" equipment maintenance.
Modular design: Customized as needed, making the "displacement stage" suitable for "your scenario".
