In the compact optical systems where every inch of space is precious, on the micro-nano characterization experimental platform in the darkroom environment, and within the highly integrated precision detection equipment, engineers have long faced an insurmountable contradiction: to achieve nanoscale ultra-precise positioning, one must incorporate full-closed-loop components such as grating rulers, but the thickness of the machine body is difficult to be made thinner; to achieve ultra-thin and compact volume, one often has to sacrifice precision and can only achieve ordinary micrometer-level positioning, which simply cannot meet the ultra-precise requirements of cutting-edge research and high-end industries.
Safin Optoelectronics, with 22 years of expertise in precision opto-mechanical engineering, has broken industry boundaries with the 7STAH01 series of high-precision electrically driven translation stages. With its unique design of "ultra-thin body + built-in high-precision grating ruler", it integrates nanoscale positioning capabilities into an extremely compact body, redefining the performance benchmark of ultra-thin ultra-precise positioners, and delivering a perfect answer that balances volume and precision for high-end ultra-precise scenarios with limited space.
Ultra-thin and compact design, easily embeddable in small workstations
The internal space of many high-end precision equipment has been meticulously planned to the millimeter. If the thickness of a translation stage is just a few millimeters thicker, the entire integrated solution may be completely overturned. The 7STAH01 series was designed from the very beginning to maximize space utilization, adopting an ultra-thin integrated body structure, with an overall thickness far less than that of conventional electrically driven translation stages with the same precision level, and can easily fit into compact optical platforms, portable high-precision detection instruments, and multi-layer stacked multi-axis positioning systems that traditional ultra-precision translation stages cannot accommodate.
The body base is reserved with standard pitch threaded holes and through holes, without the need for additional adapter plates, and can be directly fixed on the optical platform, supporting horizontal, vertical, and inverted installation methods. Many users have tested it and found that replacing it with the original ordinary micrometer-level translation stage requires no significant modification to the original equipment structure, and the system upgrade can be completed in just a few days, significantly shortening the R&D cycle of high-end precision equipment.
Grating direct measurement for nanoscale accuracy, no drift during movement
Most traditional ultra-thin translation stages adopt open-loop or semi-closed-loop control, relying on motor steps to calculate position. During operation, if there are step loss or deformation, the position deviation cannot be detected. After long-term operation, the accuracy drifts seriously, unable to meet the requirements of nanoscale ultra-precision. The 7STAH01 series directly integrates high-precision grating rulers on the stage surface, adopts a full-closed-loop control architecture, directly reads the real displacement data of the stage surface, dynamically compensates for the tiny errors in the transmission process, and the positioning accuracy reaches nanoscale.
Combined with precisely ground screw pairs for drive, the resolution performance exceeds that of ordinary rolled screw products. In combination with the precision linear slider guide rail with preload force for deflection elimination, the movement is smooth without jamming, with excellent linearity, and from the root, eliminating the accuracy loss caused by the return gap. Whether it is the nanoscale alignment of micro-nano optical components or the uniform micro-stepping feed of high-precision spectrometers, even after continuous operation for tens of thousands of hours, the grating ruler always directly reflects the real position of the stage surface, completely eliminating the risks of step loss and drift in traditional solutions, and truly achieving "when the instruction reaches the nanoscale position, the stage surface precisely stops at the nanoscale position".
Full-dimensional detail optimization, zero threshold for ultra-precision scenarios integration
Many engineers in the ultra-precision field have had similar experiences. After receiving a high-precision translation stage, they spend a lot of time debugging interfaces and compensating for installation errors, and even after several weeks of effort, they cannot reach the expected precision. The 7STAH01 series takes ease of use into consideration from the design stage, equipped with 5-phase high-resolution stepping motors, standard DB9 interface, can directly connect to the Safin 7SC10 series motion controller, perfectly compatible with mainstream programming environments such as LabVIEW and Python, supports point storage, uniform scanning, etc., complex motion modes, without the need for profound professional programming knowledge, can quickly build an automated ultra-precision position process.
The motor and the lead screw are connected through a high-quality elastic coupling, ensuring complete synchronization of the transmission and extremely low running noise, which will not interfere with the environmental state of the darkroom's ultra-precise experiments. Zero position and photoelectric switches are built into both ends of the body, supporting one-click quick zero return, and providing over-travel protection. This not only enhances positioning efficiency but also provides comprehensive protection for the equipment and high-value precision samples, avoiding costly losses caused by improper operation.
Now, the 7STAH01 series of high-precision electric translation stages have been widely applied in cutting-edge research micro-nano optical experiments, material nanoscale characterization, as well as high-end industrial semiconductor detection, precise optical element alignment and many other ultra-precise scenarios. As a benchmark product of Sefan Optoelectronics' ultra-thin and ultra-precise product line, its performance is on par with international top-level products, with a significant improvement in overall cost performance. It is also equipped with 4-hour rapid response local after-sales service and 3-year core component warranty, eliminating the need to wait for a long delivery and after-sales cycle like imported ultra-precise equipment.
Ultra-thin body, nano-steady movement. The 7STAH01 series of high-precision electric translation stages, with 22 years of precise motion control technology, have successfully incorporated the nanoscale precision of grating direct measurement into an extremely compact body, allowing space-constrained ultra-precise displacement requirements to no longer compromise between volume and precision.
