M-110, M-111 High Resolution Micro Translation Stages

  • 5 and 15 mm Travel Range 
  • 0.05 µm Minimum Incremental Motion 
  • Velocity to 2.5 mm/sec. 
  • Closed-Loop DC Motor 
  • Integrated Hall-Effect Limit Switches


Application examples: Photonics packaging, fiber optic instrumentation, fiber alignment, metrology, quality control, test equipment, micro machining.

M-110 and M-111 are ultra-high resolution motorized translation stages providing linear motion of 5 and 15 mm in an extremely compact package. They feature a precision leadscrew with sub-micron resolution and precision linear ball bearings guaranteeing < 0.5 µm straightness of travel. 

Both stages provide a cost effective solution for industrial and OEM environments. A miniature DC or stepper motor actuates motion via a backlash-compensated leadscrew / nut system and gearhead.

To meet the most critical positioning demands the DC motor is equipped with a high resolution encoder featuring resolution of 0.007 µm per count. The combination of the extremely low stiction / friction construction and high resolution encoder allows for minimum incremental motion of 50 nanometers at speeds up to 2.5 mm/sec. 

To protect your investment, non contacting Hall-Effect limit switches are integrated. Each stage includes a 0.5 m cable with 15 pin D-sub connector and a 3 m extension cable. The connector features integrated line drivers for cable lengths up to 10 meters between actuator and controller.

M-110 and M-111 can be combined to XY and XYZ systems for multiaxis alignment applications. A variety of add-on Piezo-NanoAlignment units are available, too.
