In experiments such as fiber coupling, microscopic alignment, interference measurement, and laser resonator debugging, a micrometer-level positional deviation may directly affect the optical path results. The Sefan Optoelectronics 7STM0725 ultra-precise manual translation stage is specially designed for high-precision alignment scenarios. Relying on a combination of linear guides + precision screws, it achieves a fine-tuning sensitivity of 0.002mm. It is the preferred choice for achieving micro-displacement adjustment in research laboratories and precision inspection fixtures.

It is equipped with imported high-precision ultra-thin linear guides. Compared to traditional dovetail guides, it has higher smoothness in movement, stricter gap control, and better linearity and flatness of 2μm. The swing angle control is as low as 10″. The movement process has minimal deviation, effectively avoiding angle errors during alignment, and ensuring the coaxiality of the optical path. It is paired with a finely ground screw drive, with stable transmission and sufficient driving force. Combined with the side-mounted integrated micrometer head for reading, the minimum scale is 0.01mm, and the reading is intuitive and clear. Each fine adjustment can be quantitatively traced, and uncertainty caused by blind adjustment by hand is eliminated. 。

The tabletop specification is 80×110mm. The entire machine weighs only 0.4kg. The body is compact and small, not occupying the precious space of the optical platform, yet it can support a maximum load of 20kg, balancing lightweight and carrying capacity. The lens group, beam splitter, sample fixture can all be stably mounted. The tabletop and base are arranged with standard optical installation holes. The adapter plate, mirror frame, sample holder can be assembled conveniently. It supports free stacking of the same series of translation stages, quickly building two-dimensional and multi-dimensional combination adjustment modules, adapting to the complex multi-degree-of-freedom optical path construction requirements, and expanding flexibility.

The 7STM0725 ultra-precise translation stage is widely applicable in the field of precision optics: fiber alignment coupling, interference experiments, microscopic sample positioning, laser micro-processing alignment, precise spectral scanning, photoelectric sensor calibration, etc. It is especially suitable for R&D and testing workstations with strict requirements for displacement sensitivity and linear motion. Whether it is the cutting-edge projects of key laboratories in universities or the built-in fine-tuning units of enterprise precision detection equipment, it can provide stable and reproducible displacement adjustment effects.

Every 7STM0725 produced by Saifan Optics will undergo motion accuracy and transmission smoothness verification before leaving the factory, strictly controlling gaps and consistency. The domestic ultra-precise translation solution is benchmarked against the performance of similar imported translation stages, with a short delivery cycle and convenient after-sales response. Controlling micrometer-level displacement within a small area, laying a solid foundation for high-precision optical experiments.
