Fiber alignment adjustment often requires not only X/Y/Z three-axis translation, but also precise correction of pitch and angle rotation. If multiple displacement tables are stacked and assembled, not only will the structure be cumbersome, but it will also bring complex cumulative errors, complicated calibration procedures, and poor stability. The Sefan Optoelectronics 7SWM0502 left-handed five-axis displacement table integrates three-axis translation + pitch + rotation five-degree-of-freedom adjustment. With just one unit, it can complete multi-dimensional attitude calibration, making it an excellent manual adjustment table for fiber coupling, laser alignment, passive component packaging, and optical coupling testing.

The entire machine adopts a compact integrated structure, integrating five-axis adjustment within a limited space. The axis system accuracy is uniformly calibrated at the factory to avoid deviations caused by multiple stacking assemblies. The optical path setup is more concise. The guide rails use precision linear balls combined with finely ground steel rod guides, with smooth transmission without jamming, uniform motion feel, and excellent positioning consistency. The three-axis translation is driven by a micrometer head and spring reset structure, supporting direct reading, effectively eliminating transmission backlash; the minimum translation scale is 0.01mm, the sensitivity is up to 0.002mm, and the motion swing angle is controlled within <30″, with precise and controllable micrometer-level translation adjustment.

The pitch and rotation adjustment uses M6×0.25 ultra-fine-threaded screws, combined with high-quality碟簧 reset， with stable angle locking， soft micro adjustment damping， and a ±5° pitch and rotation adjustment range， which is just suitable for fiber end face angle compensation and beam attitude correction scenarios. After adjustment， it is not easy to shift， and the coupling peak can be stably maintained. The vertical axis uses rigid drive for elevation， different from the ordinary spring-supported Z-axis， with stronger bearing capacity， a rated load of 2.5kg， and a self-weight of only 1.15kg. It combines lightweight and structural rigidity， and is not prone to deformation or drift during long-term debugging.

The human-machine operation layout continues the mature design of the series. The two horizontal axes' micrometers are arranged on the same horizontal plane. The left-handed model is suitable for left-handed operation habits and can be paired with the right-handed 7SWM0501 model for symmetrical optical paths and dual fiber synchronous coupling conditions. During debugging， there is no need to frequently switch hands， and the operation is smooth and efficient. The tabletop size is 74×60.5mm， with standard optical installation holes reserved， which can directly accommodate fiber clamps， collimators， and optical lenses， without the need for additional adapters， and is suitable for laboratory research and batch assembly on the production line.

In fiber coupling debugging， beam offset and angle skew are common reasons for alignment failure. Traditional three-axis tables can only adjust position， and angle deviations require additional tilt tables. There are many components and a long debugging chain， which is prone to losing lock when touched. The 7SWM0502 integrates translation and angle adjustment into one， synchronously adjusting position and attitude， significantly reducing alignment time and lowering optical path maintenance costs. Whether it is fiber alignment coupling， waveguide component alignment， micro-optical assembly adjustment， or photoelectric detection optical path calibration， a five-axis displacement table， which combines precise position and angle adjustment， simplifies complex fiber coupling work.
