In the nanoscale lithography of semiconductor wafers, a 0.5-micron lateral displacement deviation can lead to circuit pattern deviation and the entire wafer being scrapped; in the assembly of multiple optical lenses, a sub-micron level planar tilt can cause the optical axis to fail to converge, resulting in a sharp drop in imaging clarity; in the automatic scanning of biological samples, a slow translation speed can slow down the 3D reconstruction efficiency and prolong the new drug development cycle by several months...
For research and industrial scenarios that pursue "perfect planarity", "translation" is no longer just a simple "left-right movement", but has become the "core ruler" determining the accuracy of the two-dimensional coordinate. The "handshake error" of traditional manual translation stages, the "response lag" of semi-automatic platforms, and the "insufficient rigidity and thermal drift" of ordinary electric stages have become the "invisible gap" restricting precise manufacturing and scientific exploration.
Savant Optics has been deeply engaged in precise motion control for 15 years, with the mission of "making every translation precise and controllable", and has launched a full range of high-precision electric translation stages - using "nanoscale planar accuracy + high-speed stable control + strong load adaptability" to unlock "translation freedom" for precise manufacturing and scientific experiments.
Savant High-Precision Electric Translation Stage: The Three Core Principles of "Planar Precision"
In the field where "a hair's breadth of difference in the plane leads to a thousandfold difference in the result", Savant Optics' high-precision electric translation stage, with its "precision, speed, and intelligence" three-in-one technological barrier, has become the "preferred choice for plane positioning" of industry customers.
1. Precision: A leap from "micron-level" to "nanometer-level", making the plane error zero
The soul of the translation stage is "flatness" and "accuracy". The Savant high-precision electric translation stage adopts a linear motor/high-precision ball screw + cross roller guide rail transmission system, combined with a nanoscale optical grating (resolution 0.01 μm) and a full closed-loop servo control algorithm, achieving repeat positioning accuracy of ±0.1 μm, absolute positioning accuracy of ±0.5 μm (custom models can reach ±0.05 μm), far exceeding industry standards (usually ±1 μm).
Nano-level fine-tuning capability: Supports "coarse adjustment + fine adjustment" dual mode switching, with rapid coarse positioning (speed up to 1000 mm/s), fine adjustment step size of 0.001 μm, meeting the needs from macro assembly (such as coarse alignment of optical components) to microscopic calibration (such as adjustment of electrode spacing of quantum chips);
Zero gap and anti-drift: The pre-tightening gap elimination structure of the cross roller guide rail + the non-contact transmission of the linear motor completely eliminates mechanical gap; the built-in temperature sensor compensates for thermal deformation in real time, with 24-hour displacement drift < ±0.2 μm, ensuring the "time dimension consistency" of long-term testing;
Multi-axis linkage zero coupling: When X/Y dual axes or multi-axis linkage occurs, the algorithm compensates for the coupling error of plane motion to achieve "pure two-dimensional plane positioning", avoiding interference between "X movement" and "Y motion", and the plane error < 1 μm/m².
2. Speed and Load: Flexibility in both rigidity and flexibility, suitable for "fast-paced" and "heavy tasks"
Precision does not mean "slow motion". Savant high-precision electric translation stage breaks the stereotype that "high precision requires low speed":
High speed response: Equipped with high-performance linear motors (peak thrust 500 N) or servo motors (optional direct drive module), the fastest translation speed is up to 1500 mm/s with an acceleration of 5g, meeting the dual strict requirements of "speed + precision" for semiconductor packaging (requiring instantaneous positioning) and laser processing (requiring high-frequency scanning);
Load-free: The high-strength aluminum alloy frame + honeycomb-shaped reinforcement structure, with a maximum load capacity of 300 kg (custom models can exceed 500 kg), even when equipped with heavy optical platforms or precision molds, still maintains "zero distortion" during translation (plane distortion < 2 μm); Low vibration characteristics: Through finite element analysis to optimize the transmission structure, the vibration amplitude during operation is less than 0.5 μm, avoiding damage to precision samples (such as thin film sensors, biological slices) due to vibration.
3. Intelligent control: Evolution from "single machine translation" to "system collaboration"
The Sefan high-precision electric translation stage is not only an "execution terminal", but also an "intelligent plane brain":
Open control system: Supports industrial protocols such as EtherCAT, Modbus TCP, USB, and is compatible with programming environments such as LabVIEW, Python, and C++. It can seamlessly connect to customers' automated production lines or research instruments (such as confocal microscopes, atomic force microscopes);
One-click programming and trajectory planning: Has a graphical interface, supports "position-time" curve presetting (such as uniform translation, sinusoidal oscillation, helical scanning), allowing researchers to complete complex translation processes (such as multi-point stress loading in material fatigue tests) without code;
Multiple safety protections: Standardly equipped with collision sensors (emergency stop when encountering resistance), soft and hard limiters (preventing overtravel), power-off self-locking (maintaining the current position), and combined with real-time status monitoring (displacement, speed, load, temperature), making the operation "zero-risk".
Modular design: Customizable as needed, making the "translation stage" suitable for "your plane scenarios"
Sefan Optoelectronics understands that the "plane requirements" in different industries vary greatly. We provide a full range of standardized products + deep customization services, covering all scenarios from "desktop level" to "production line level":
By axis number: Single axis (X), double axis (X-Y), multi-axis (including rotating axis θ, achieving combined motion of plane + angle), meeting requirements such as one-way movement, two-dimensional scanning, and compound positioning;
By travel: Short travel (10-100mm, suitable for microscopic operations), medium travel (100-500mm, suitable for optical component assembly), long travel (500-2000mm, suitable for large-sized workpiece inspection);
By environment: Standard model (laboratory/洁净车间)， dust-proof and waterproof model (industrial site)， vacuum model (semiconductor coating)， low-temperature model (-40℃ environment)， explosion-proof model (chemical environment)， operating stably in extreme environments.
