In optical debugging work, many scenarios require a larger two-dimensional movement range without sacrificing structural rigidity and positioning stability. The 13mm travel rigid platform is suitable for short-distance fine-tuning, while the 7SWM02225 rigid left-hand two-axis translational platform, with a 25mm travel range and a roller V-shaped guide rail with a strong rigidity structure, complements the series' need for large travel and high-load manual two-dimensional adjustment. It pairs with the right-hand model 7SWM02125 and becomes a main displacement component for optical path setup, component coupling, and sample detection, balancing travel, rigidity, and accuracy.

It continues the core design of the rigid series, using a precise linear roller + finely ground V-shaped guide rail structure. Compared to ball guide rails, the roller linear contact has stronger bearing and anti-bias load capacity, and the guide rail is less prone to deformation under pressure, remaining smooth and uniform during repeated adjustments over a long period, without any jamming or missed positions. The oscillation error is controlled at <30″, and the two-axis orthogonal accuracy is stable and reliable. When the platform is equipped with optical components such as spectroscopic mirrors, coupling components, and small detectors that are relatively heavy, it will not undergo hidden deformation due to load pressure, avoiding common experimental problems such as light spot drift and poor alignment repeatability. The rigidity advantage is transformed into stable alignment results.

The core adjustment unit is a micrometer head drive combined with a spring reset mechanism, with a minimum scale of 0.01mm and a sensitivity of up to 0.002mm. It supports direct reading and effectively eliminates transmission backlash. Even within the 25mm full travel range, the micrometer-level fine adjustment remains controllable and reproducible. Whether for large-scale coarse scanning to find the light spot position or for the micro-meter-level fine alignment at the end, a single platform can complete the task, eliminating the need for multiple disassembly and connection operations, significantly simplifying the optical path debugging process. The rated load is 4kg, the self-weight is 0.6kg, the platform surface is 65×65mm, and a larger installation platform can directly accommodate more optical accessories. The tool arrangement is more flexible, suitable for complex two-dimensional testing module setups.

The human-machine operation maintains a unified friendly layout of the series, with a dedicated left-hand version, where the two-axis micrometers are placed on the same horizontal plane, with a unified debugging perspective. A single hand can independently complete X and Y two-way adjustment without switching hands or flipping the tooling, maintaining a stable hand feel during long-term continuous alignment debugging, reducing debugging fatigue. The platform and base are reserved for standard array installation holes, compatible with optical brackets, rotating tables, heightening tables, angular displacement tables, etc., and can be used alone or freely stacked to form a multi-dimensional adjustment system, flexibly adapting to university research optical paths, optical communication component coupling, two-dimensional material characterization, industrial micro-sample visual inspection, and teaching experimental platform upgrades, etc.

Many optical path schemes are limited by short travel translational platforms and can only be split into multiple adjustment frames, resulting in a cumbersome structure and more cumulative errors. The 7SWM02225 rigid two-axis translational platform was specifically designed to address the pain point of "wanting a large travel but fearing insufficient rigidity and unstable positioning." It forms a high-low combination with the light-lively series and also forms a travel梯队 with the 13mm travel model in the same series： for lightweight and small-space selection， choose the light-lively series； for short travel and high rigidity， choose 7SWM02213； for a larger movement range and larger installation platform， choose this 25mm travel 7SWM02225.

With rigidity to support the load， long travel to expand the debugging boundary， and micrometer accuracy to lock the target position. If you are building an optical path system that requires large-scale two-dimensional adjustment， carrying heavy optical components， and having requirements for long-term stability and precise alignment， the 7SWM02225 rigid two-axis translational platform is a reliable choice that balances travel， rigidity， and accuracy， ensuring each large-scale scanning and fine alignment is stable and accurate.
