In the processes of precise optical path construction, microscopic focusing, fiber coupling, and sample calibration, many high-precision debugging scenarios are most sensitive to the occurrence of horizontal lateral displacement during the lifting process. The inherent lateral clearance of the scissor-type lifting platform can easily introduce errors in high-sensitive optical alignment. The 7SVM0413 direct-action lifting platform adopts a precise linear guide structure and focuses on short-stroke vertical precise adjustment, providing a reliable solution for experimental scenarios with strict coaxiality requirements.

The entire machine uses an integrated base with a precise linear guide pair, driven by a screw rod, with the movement direction strictly along the vertical axis. The lateral jitters during the lifting process are extremely low. With a 13mm effective travel, it is just suitable for fine height difference adjustment, a 0.01mm adjustment resolution, uniform and smooth handwheel damping, no sticking during rotation, and small backlash. It can quickly complete coarse positioning and also slowly rotate the handwheel for micrometer-level fine alignment, suitable for the height calibration of optical lenses, fiber probes, micro samples, and photodetectors.

The structure is rigid and the guide pair has been processed for clearance elimination. Under the rated load, the lifting is stable and unlikely to tilt or sway. It is equipped with an independent locking knob, which locks after being adjusted to the target height. The positioning locking is firm and can withstand slight environmental vibrations. Long-term static observation and static calibration experiments are less likely to experience position drift, eliminating the need to repeatedly re-align the optical path, effectively saving debugging time and ensuring the consistency of test data.

Following the modular design concept of optical and mechanical components, the tabletop and base plate are arranged with standard optical installation holes, and both sides can be used as installation references. It can directly be equipped with sample holders, lens seats, fiber clamping components, and can also be combined with translation tables and rotation tables for stacking and forming a multi-degree-of-freedom compound adjustment platform, compatible with optical platforms and optical breadboards. The body is compact and small, suitable for layout in space-constrained integrated optical paths and small detection workstations. The layout is flexible, and the modification difficulty is low.

The applicable scenarios cover university research laboratories, photonic enterprises' R&D and testing workstations: microscopic imaging focusing, laser optical path coupling, optical component calibration, micro-area sample characterization, teaching optical experiments, non-standard detection workstations. It is especially suitable for precise systems that are sensitive to lateral displacement on the opposite side of the optical path and do not allow horizontal offset during lifting.

Vertical precise adjustment, straight up and down, without any redundant swaying. The 7SVM0413 direct-action lifting platform, with stable linear guidance, maintains the accuracy of each tiny height adjustment, is an excellent choice for compact optical paths with short-stroke vertical adjustment.
