When the experiment requires a larger adjustment stroke while not sacrificing positioning rigidity and repeatability, the 7STM04250 Resolute Manual Linear Platform is an ideal solution that balances stroke, rigidity, and stability. Unlike small-stroke linear platforms, this product has an effective stroke of 50mm, equipped with a center-mounted micrometer head, and is intuitive and easy to operate, making it highly suitable for the construction of optical systems that require large-scale coarse adjustment and micrometer-level fine adjustment.

The guide rails adopt a cross-roller + V-shaped steel guide structure, with good linear running performance, longer wear resistance, and less prone to jamming or precision degradation during repeated adjustment. The steel tabletop is a major feature of it, with strong rigidity and corrosion resistance. Compared to the aluminum alloy tabletop, it is more suitable for continuous debugging and frequent disassembly in industrial environments, less likely to be deformed under pressure, and has more stable long-term usage performance.

It has a built-in spring clearance compensation and reset structure, effectively eliminating transmission clearance, and the adjustment is precise and quick. The micrometer head has a minimum scale of 0.01mm, a sensitivity of 0.002mm, and a positioning accuracy of 0.003mm. Even with a large stroke, it still maintains the micrometer-level adjustment capability. The spot alignment, sample scanning, and fiber coupling can all be accurately achieved.

The tabletop size is 110×120mm, with ample installation space. The center load is 5kg, and it can securely accommodate optical lenses, spectrometers, fixtures, small photodetectors, etc. The tabletop and base are arranged with standard optical installation holes, which can be directly fixed on the optical platform or freely stacked with the same series of displacement platforms to quickly form two-dimensional, three-dimensional, and multi-dimensional adjustment components, and flexibly adapt to complex optical path layouts.

It is widely applicable for laser debugging, spectral testing, microscopic inspection, photonic calibration, teaching optical experiments, and sample alignment in small-scale photonic production lines. Many scientific research and industrial customers, when selecting, need both a sufficient adjustment range and the delivery timeliness and cost advantages of domestic equipment. The 7STM04250 effectively fills this demand, replacing imported similar steel tabletop linear platforms, significantly reducing equipment procurement budgets.

Each 7STM04250 is factory-tested for accuracy and stabilized in terms of time, and the mechanical consistency is controllable. The Resolute series of displacement platforms from Saifan Optics provide a stable and reliable manual adjustment solution for long-stroke precision displacement requirements, allowing for both large-scale movement and micrometer-level fine adjustment.
