During the optical path debugging process, many experiments require not only sufficient moving travel but also smooth adjustment force and clear, controllable readings. The Sefan Optoelectronics 7STM0675 manual translation stage, relying on the dovetail guide rails combined with the helical gear rack drive structure, features a 75mm long travel design, balancing large driving force, high load capacity, and micrometer-level positioning accuracy. It is a highly practical one-dimensional displacement adjustment solution for optical setup, sample calibration, and detection fixtures.

It adopts the classic dovetail guide rail structure, which is rigid and has a maximum load capacity of 20kg. The lens group, spectroscope components, sample fixtures, etc., are not prone to deformation and remain stable even after long-term repeated adjustments. Different from screw drive, the helical gear rack drive provides greater output driving force, with large handwheels on both sides, which have a light and smooth turning feel, without any jamming or stickiness during adjustment, and are not prone to fatigue during long-term debugging. The platform integrates a vernier reading structure, with a minimum reading of 0.02mm and a positioning accuracy of 0.01mm. It can achieve quantitative displacement adjustment, eliminating the need for repeated estimation of alignment, effectively reducing the trial-and-error cost of optical path calibration.

The platform size is 65×110mm, and the platform and base are fully equipped with standard optical installation holes. The adapter plate, mirror frame, and sample holder can be directly assembled. The installation and fixation are simple and quick. The same series of translation stages support free stacking combinations, enabling rapid construction of two-dimensional and multi-dimensional adjustment modules, and flexibly adapting to various complex optical path layouts, with strong scalability and adaptability to changing experimental scenarios. The self-weight is only 0.8kg, balancing structural strength and lightweight, facilitating flexible layout on optical platforms and detection equipment interiors. It can also be used in conjunction with the 7MB25 base plate.

The 7STM0675 is suitable for a wide range of scenarios: university research and teaching optical path setup, laser alignment debugging, thin film sample scanning tests, industrial vision calibration, photoelectric sensing detection fixtures, etc. It can perform stable and reliable displacement performance in various laboratory routine research and tests, as well as manual fine-tuning positions in small-batch automated equipment. It can meet the requirements of large and medium travel manual adjustment. This 7STM0675, with its 75mm practical travel, high load capacity, and readable quantitative adjustment features, complements the demand for manual adjustment with large travel, and is a cost-effective domestic optical machine component. The delivery and after-sales response are more convenient, providing stable and controllable displacement support for precise optical systems.
