Rotary Micro Stages
m3-RS Rotary Smart StageS
New Scale has created a number of rotary micro stages and positioning modules featuring our patented piezoelectric motors along with integrated position sensors, bearings, drive electronics and embedded firmware. The M3-RS Series of completed designs are available for special order.
Please contact us about custom development of rotary micropositioning stages.
NOTE: Standard M3-RS-U models are available by special order only. Existing customers please contact tech support.
SPECIAL ORDER: M3-RS-U-360 Rotary Microstage
This smart stage is only 12 mm in diameter including the embedded controller. It was developed for a scientific application requiring precise rotational positioning in a limited space. It delivers continuous 360° rotation.
This design is available for special order in volumes. It can be used as a basis for custom rotary modules for beam alignment and positioning, optical tuning with gratings or filters, and sample alignment.
Application Examples
Application Example: Mirror Positioning
An M3-RS stage as a single-axis mirror positioning system
Application Example: Beam Steering
Two M3-RS stages in a two-axis, two-mirror beam steering system
