The construction of the optical system cannot do without stable and low-offset precision displacement adjustment components. The Sefan Optoelectronics 7STM02125 manual translation stage, which combines long travel and high precision adjustment, is a cost-effective domestic choice for scenarios such as optical path alignment, sample positioning, and optical assembly and adjustment.
The 7STM02125 adopts a steel ball precision guideway structure, with smooth movement and little vibration. It is combined with a spring deflection mechanism to effectively reduce the return gap of the screw transmission and avoid empty travel during fine adjustment, ensuring the consistency of positioning. The fine-thread differential screw drive provides a delicate adjustment feel and is suitable for repeated fine alignment operations. This translation stage has a travel of 25mm, a tabletop of 34×34mm, a compact structure, and a light self-weight. The maximum load capacity can reach 1kg. While maintaining the travel advantage, it does not occupy excessive installation space.
The tabletop and base are designed with standard optical installation screw holes, ensuring strong compatibility. It can be used alone as a single-axis adjustment unit or stacked with other series translation stages to quickly build XY, XYZ multi-dimensional adjustment tables, suitable for various optical machine structure schemes. With a pure manual structure, it does not require wiring or a matching drive controller. It can be debugged after unpacking, eliminating the cumbersome power-on and parameter setting processes. It is suitable for laboratories to quickly build testing systems.
The applicable scenarios include laser optical path debugging, optical lens fine adjustment, microscopic sample displacement, spectral detection, optical component testing, university optical teaching experiments, and small visual inspection fixtures, etc. Compared with imported similar displacement stages, the 7STM02125 has a more friendly purchase cost, a short supply cycle, and convenient after-sales support, while maintaining the same level of accuracy and stability.
As a classic model of the Sefan Optoelectronics 7STM series, the 7STM02125 continues the series' reliable processing technology, suitable for research institutes, university laboratories, and optical enterprises for prototype development, experimental verification, and small tooling assembly. When you need a 25mm travel, compact and lightweight manual precision translation stage, it is a reliable and safe selection option.
