Linear Micro Stages

M3-LS Linear Smart Stage: Micro positioning stage with embedded controller

The M3-LS Linear Smart Stage is a direct-drive, high-precision micro stage with built-in controller. It is designed for fast, simple integration into miniature OEM systems.

This “smart stage” has all drive electronics integrated right into the compact stage housing – no external board needed! It offers unmatched precision, stability and ease of use.

M3-LS-3.4-15 Linear Micro Stage

This longer-travel, higher-load Smart Stage (micro stage with integrated controller) has low power use and 15 mm of travel.

M3-LS-1.8-6 Linear Micro Stage

This ultra-compact Smart Stage (micro positioning stage with integrated controller) has low power use and 6 mm of travel.

Embedded Controller

A Smart Stage has the controller built right in, for smallest system size and simplest system integration. Learn more

Smallest size, low power, fast integration into OEM systems


  • Integrated smart module: no separate electronics – USB, I2C or SPI interface
  • Small size: from 29 x 20 x 10 mm to 32 x 32 x 11 mm including controller
  • High resolution: 0.5 µm
  • Long stroke: 6 mm or 15 mm
  • Absolute encoding: no homing needed
  • Low voltage, low power use
  • High repeatability and low runout
  • Quiet: so quiet you can hear a pin drop (video)


Unmatched precision, stability and ease of use

The piezo-driven positioning stage has 0.5 µm 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 M3-LS micro stage has high stiffness and lateral stability, no backlash, and less than 10 µm runout over its full travel range.

Direct input via USB, I2C or SPI

The M3-LS Smart Stage – a linear stage with embedded controller – accepts direct input of simple high-level motion commands. It is the only linear micro stage that can be driven directly from a system processor via standard I2C or SPI interface.

Alternatively, a USB adapter enables connection to a PC, with New Scale Pathway™ software providing an easy-to-use graphical user interface. You can control multiple positioning stages from a single screen for interactive operation. Employ the intuitive script generator to create command sequences for automated operations.

Low power use for hand-held systems

The ultra-compact M3-LS-1.8 Linear Smart Stage can be powered by USB or standard batteries.

The longer-travel M3-LS-3.4 Linear Smart Stage can run on batteries or a low-cost DC power supply.

The integrated piezoelectric motor holds position without using power. The internal electronics can be switched to sleep mode for extreme low-power applications.


A tiny all-in-one positioning stage that can be powered by standard batteries, the M3-LS linear micro stage is ideal for motion in hand-held and portable instruments.

  • Create miniature microscopes and spectroscopy instruments.
  • Miniaturize systems for micro assembly and biomedical probing or sampling.
  • Use in high resolution tuning systems, targeting systems and UAV/UGV controls and optics.
  • Develop miniature camera systems and more.

Easily configure multiple M3-LS microstages into XY and XYZ configurations.
