The M3-LS Linear Smart Stage is a direct-drive, high-precision micro stage built for fast, simple integration into miniature OEM systems. All drive electronics are integrated right into the compact stage housing – no external board needed! The piezo-driven stage has 0.5 micron resolution for precise, repeatable positioning of optics, probes, sensors and more. Absolute encoding removes the need to home the stage on power-up, eliminating errors and disruptions in processes and experiments.

The unique linear slide has uniform and very low friction, even under high direct loads and side loads. Six ball bearings in a kinematic “v” guide-way eliminate cage creep and friction spike problems common in other micro stages. The M3-LS has high stiffness and lateral stability, no backlash, and less than 10 micron runout over its full travel range. The stage accepts simple high-level motion commands via standard serial interface. Use the USB adapter to power and control multiple stages from a single user interface, or use the intuitive script generator to easily create command sequences for automated operations.

The M3-LS stage can also be driven directly from your system processor via standard I2 C or SPI interface. The M3-LS Linear Smart Stage needs only 3.3 V DC and uses less than 0.75 W typical when moving. It can be powered by USB or standard batteries. The integrated piezo motor holds position without using power and the internal electronics can be switched to sleep mode for extreme low-power applications. M3-LS stages are easily configured into two-axis and three-axis systems. Developer’s kits are available at Digi-Key and Mouser.
