New Scale Technologies, Inc. has 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 in medical, commercial and industrial instruments.
The new lifetime specification 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, more than four times the typical load presented by the standard mirror used for beam steering.
Applications
- Ideal for beam steering and mirror positioning applications where precise, point-to-point positioning or dynamic scanning up to 100 Hz is needed
- Medical instruments such as surgical lasers and fluorescence microscopes
- Industrial systems for 3D measurements and remote sensing
- Optical communications systems
- Obstacle detection and tracking systems for robots and drones (UAVs)
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.
