In experimental scenarios such as spectral scanning, long-distance sample movement detection, and large-scale optical path construction, it is often necessary to consider a manual displacement solution that can accommodate a 200mm ultra-long stroke, stable load-bearing, and accurate reading. The 7STM06200 translation stage from Saifan Optoelectronics, the largest in the series, relies on dovetail guide rails combined with helical gear rack drive structure, providing reliable support for optical systems requiring large-scale manual adjustment.

The 7STM06200 features high-stiffness dovetail guide rails, a solid and stable structure, with a maximum load capacity of 20kg. When equipped with optical lens groups, spectrometric components, and large sample holders, it is less likely to deform and maintains stable linear movement during repeated adjustments. The helical gear rack transmission provides sufficient driving force, different from the screw structure, and enables smoother and more force-efficient oscillation over long distances. It is equipped with large handwheels on both sides, providing a light and smooth operation feel, and continuous movement of several hundred millimeters does not cause fatigue. The platform is integrated with a vernier scale, with a reading of 0.02mm and a positioning accuracy of 0.01mm. It can achieve quantitative displacement calibration, eliminating the need for repeated estimations for alignment, significantly reducing the trial-and-error cost of long-distance scanning and debugging.

The platform size is 90×240mm, with standard optical installation holes all over the platform and base. The adapter plate, mirror frame, sample holder, and workholding fixture can be directly assembled. Installation is convenient, and it is compatible with the standard hole positions of optical platforms. It comes with a locking wrench, which locks and fixes after the position is adjusted, ensuring a reliable lock, avoiding the platform from sliding or shifting after the adjustment. It also supports stacking combinations with other displacement stages of the same series to quickly build two-dimensional and multi-dimensional adjustment modules, flexibly adapting to complex optical path layouts, and has strong scalability, suitable for various changing experimental scenarios. The self-weight is 2.3kg, balancing rigidity and portability, making it convenient for disassembly, transfer, and relocation between experimental workstations.

It is highly suitable for long-distance scanning tests in university research, R&D of optical enterprises: film sample scanning, spectral acquisition displacement adjustment, large-scale laser optical path alignment, visual inspection fixture alignment, construction of large-scale optical tools, etc. Many hand-operated positions that require large-scale coarse positioning and precise reading are exactly filled by this translation stage, which meets the long-distance demand, is stable and durable, and is simple to maintain.

Before each displacement stage leaves the factory, it undergoes transmission clearance, motion smoothness, and scale verification to ensure the consistency of each displacement. The 7STM06200, with its core advantages of 200mm long stroke, high load capacity, and accurate reading, solves the problem of long-distance manual debugging. It is a domestic optical component, with stable delivery and convenient after-sales response, making it a practical choice for long-distance optical position displacement setup.
