The LBTEK MP-FCS303 three-axis stage features a modular, interchangeable drive design, offering 4 mm of travel on each of the X, Y, and Z axes. The top plate integrates precision grooves to enable fast and accurate alignment and positioning of Multi-Axis Stages accessories. This series replaces traditional guide rail structures with parallel flexure mechanisms, effectively eliminating friction and mechanical backlash, and delivers thermal stability of 1 µm/°C, significantly reducing interference from ambient temperature changes on precision alignment. All adjustment components are coupled and secured to an integrated base, minimizing cross-talk among the three axes and ensuring positioning accuracy during independent motion of each axis. The modular drive design supports actuator interchangeability, allowing users to flexibly select manual micrometer heads, Stepper Motor actuators, or piezoelectric actuators according to application requirements. It is particularly well suited to complex applications requiring customized drive solutions, such as multi-axis automated alignment and hybrid manual/motorized adjustment.

The LBTEK MP-FCS323 three-axis NanoMax stage system is specifically designed for optical coupling applications requiring sub-micron repeatability precision. All X, Y, and Z axes are pre-equipped with differential micrometer drives, supporting dual-speed adjustment of "coarse + fine", with a coarse adjustment travel of 4 mm and a fine adjustment travel of 300 µm. The coarse adjustment knob provides a rate of 500 µm/rev with a scale resolution of 5 µm; the fine adjustment knob provides a rate of 50 µm/rev with a scale resolution of 0.5 µm. It is also fitted with a rubber thermal insulation sleeve that effectively reduces interference from hand heat conduction on precision adjustment. The parallel flexure design ensures smooth, continuous motion and long-term stability, while the differential drive structure ensures precision without compromising ease of operation. The top plate incorporates precision grooves to facilitate rapid and accurate alignment of Multi-Axis Stages accessories. All adjustment components are coupled and secured to an integrated base, minimizing crosstalk among the three axes. The system adopts a modular, interchangeable drive design. Differential micrometers are mounted through quick-connect interfaces and can be removed and replaced with other drive types at any time, flexibly adapting to different application scenarios.

The pitch-yaw stage is mounted on the three-axis translation stage.

The FMA-05A1 features SM05 (0.535"-40) internal threads, allowing SM05-threaded components to be integrated into a flexure translation stage system. Typical applications include sealing the optical path using Ø1/2" Lens Tubes. The compact L-shaped design ensures that the optical axis is positioned 12.5 mm above the translation stage. It is secured to the top plate of the translation stage with mounting bolts, which are machined with flat sides to facilitate insertion or removal of the mount without the need to remove the fixture.

The FMA-RMSA12 features standard RMS (0.800"-36) internal threads. The RMS thread is the technical standard Objective Lens interface thread in the optics industry, ensuring broad compatibility with a wide range of Optical Components. Its compact L-shaped design places the optical axis 12.5 mm above the translation stage. With mounting bolts securing it to the top plate of the translation stage, Optical Components can be installed and replaced quickly, making it ideal for Objective Lens mounting in fiber coupling applications.
