Many microscopic, fiber coupling, and sample characterization experiments not only require alignment in the XY plane, but also need fine Z-axis depth adjustment. If a dual-axis translation stage is assembled with independent elevating stages, not only will the stacking height be large and the platform space occupied, but also multiple assembly groups will introduce cumulative errors. The 7SWM03213 lightweight series left-handed three-axis translation stage continues the compact and lightweight design of the lightweight series. One stage integrates XYZ three-axis precise displacement, with three-axis integrated molding, excellent orthogonal accuracy, and is a convenient choice for three-dimensional precise assembly in space-constrained scenarios.

As the left-handed three-axis translation stage of the lightweight series, it is equipped with precise linear ball bearings + finely ground steel rod guide rails. The transmission damping is uniform and smooth, the adjustment feels delicate, without jamming or virtual positions, and the swing angle is less than 30″, ensuring the coaxial consistency of the three-axis movement. The three-axis travel is unified at 13mm, with a minimum scale of 0.01mm, a sensitivity of 0.002mm, and it can be directly read with a micrometer head drive and spring reset mechanism. It can directly read the measurement, efficiently eliminate transmission backlash, and seamlessly perform coarse scanning positioning and micrometer-level fine adjustment, ensuring stable and controllable alignment of the light spot, focus adjustment, and three-dimensional sample positioning.

Unlike ordinary assembly-type three-axis stages, this product's Z-axis adopts a rigid drive lifting structure, with a higher load-bearing capacity than the conventional spring lifting scheme. The rated load is 2.5kg, and the self-weight is only 0.9kg. It combines lightweight body with reliable load-bearing. The standard installation hole position of 60.5×39.6mm on the tabletop allows for standard installation without additional adapter plates. It can directly be equipped with sample holders, fiber clamps, and small mirrors, and can also be freely combined with rotating stages and angular displacement stages, quickly building a multi-dimensional composite adjustment system, suitable for light-load three-dimensional debugging scenarios such as light path coupling, microscopic imaging, two-dimensional material sample detection, and university teaching experiments.

The ergonomic design continues the unified series design. The left-handed version has the micrometer heads of the two axes arranged on the same horizontal plane, with consistent adjustment perspectives. It can be adjusted in both X and Y directions with one hand, and the Z-axis is independently controlled for depth focusing. There is no need to repeatedly switch hands or turn over the tooling, allowing for smooth and non-fatiguing long-term continuous alignment debugging. The right-handed version of the 7SWM03113 of the same series can be paired to facilitate symmetrical layout of the tooling and synchronous debugging of both workstations.

The lightweight three-axis stage and the lightweight two-axis stage form a paired combination: for only planar light spot alignment, choose the 7SWM01 lightweight two-axis; for synchronous control of planar position and depth height, and three-dimensional spatial alignment, 7SWM03213 is the more suitable choice. The integrated structure eliminates the need for multiple displacement stages to be assembled in series, reducing error sources, simplifying the optical path layout, and making the optical platform more concise and regular, especially suitable for small optical paths, prototype test tooling, and compact microscopic module setups in research groups.

The lightweight body supports three-dimensional accuracy, and the integration simplifies the optical path setup. If you are looking for a compact, easy-to-operate, backlash-controllable, and orthogonal-stable manual XYZ translation stage, the 7SWM03213 lightweight three-axis translation stage, with a compact structure, achieves three-micron adjustment in the three axes, making each spatial alignment and depth focusing precise and从容.
