Ideal for embedded motion in industrial and medical instruments, the M3-RS-U Rotary Smart Stage features smallest system size, fastest integration, and now longer life

New Scale Technologies, Inc. has significantly increased the lifetime specification for its M3-RS-U Rotary Smart Stage, a precision rotary micro stage with embedded controller. The new specification of 100 million random positions underscores the utility of these compact, all-in-one motion modules for integrating embedded motion inside medical, commercial and industrial instruments.

“These precision rotary smart stages are proven to make great products smaller, with the built-in controller supporting easy integration and fast time to market,” said New Scale CEO David Henderson. “The increased lifetime specification makes the selection decision even easier for product designers who need to embed motion in their portable and hand-held systems.”

The new lifetime specification for the rotary micro stage is based on performance testing in which standard M3-RS-U Rotary Smart Stages achieved more than 160 million random positions within two billion degrees of total rotation. Test conditions included a moment of inertia load of 4 g-mm2 on a horizontal axis. This is more than four times the typical load presented by the standard mirror used for beam steering.


M3-RS-U Rotary Smart Stages are ideal for beam steering and mirror positioning applications that require precise, point-to-point positioning or dynamic scanning up to 100 Hz. Applications include medical instruments such as surgical lasers and fluorescence microscopes, industrial systems for 3D measurements and remote sensing, optical communications systems, and obstacle detection and tracking systems for robots and drones (UAVs).

Rotary Micro Stage Specifications

The M3-RS-U Smart Stage is less than 12 mm in diameter including the controller. It features continuous 360 degree rotation at up to 1100 degrees per second with accuracy of 0.25 degrees. An internal absolute position sensor has 0.025 degree closed-loop angular resolution. The micro stage holds position with zero power and no jitter.
