In the processes of optical system setup, sample scanning, and optical path alignment, many scenarios require a wide adjustment range while maintaining the ability to make micrometer-level fine adjustments. The Sefan Optoelectronics 7STM0550 manual translation stage, with a 50mm long travel design, balances the adjustment range and positioning accuracy. It is a practical displacement unit for research laboratories and optical R&D production lines.

The guide rails adopt a cross-roller guide structure, which runs smoothly, has excellent straightness, is wear-resistant and fatigue-resistant. After repeated pushing and pulling adjustments for a long time, it is unlikely to get stuck or loosen. The positioning repeatability is stable. It is equipped with a backlash spring structure, which effectively suppresses the transmission backlash. When turning the micrometer head, the feel is continuous, the fine adjustment feedback is clear, and the workload of repeated calibration is reduced.

The standard configuration includes a precision micrometer head drive with a minimum scale of 0.01mm, supporting micrometer-level fine alignment. After the large range of coarse adjustment is completed, the optical spot, sample, and fiber optic can be finely aligned. The operation logic is in line with the debugging habits of researchers. The tabletop is reserved with standard optical installation holes, which are compatible with optical platforms, adapter bases, mirror frames, and other displacement stages of the same series. It can be used independently on a single axis or combined with multiple stages to build a two-dimensional or three-dimensional adjustment platform, suitable for complex optical path layouts.

The tabletop has solid bearing performance and can carry optical lenses, lenses, sample fixtures, small photodetectors, etc. It is suitable for teaching experiments, project research, and small sample testing scenarios. The aluminum alloy tabletop is lightweight and designed with controllable self-weight. When stacked and assembled, it will not impose excessive load on the lower displacement structure. The assembly is flexible.

The applicable scenarios include laser optical path debugging, spectral detection, microscopic imaging, fiber coupling, optical calibration, and optical teaching experiments, etc. Compared with imported similar translation stages, the 7STM0550 has a shorter supply cycle, more convenient after-sales response, and significantly reduces the equipment procurement cost of research projects.

The displacement stage of Sefan Optoelectronics undergoes precision detection and aging treatment during the factory process, ensuring good product consistency. The 7STM0550 translation stage integrates long travel adjustment and precise fine adjustment, providing stable and worry-free displacement support for various optical experiments, making large-range movement and high-precision alignment no longer a dilemma.
