FIBER POSITIONER PROJECT COMPLETED BY NEW SCALE TECHNOLOGIES

New Scale Technologies, developer of the smallest piezo-based motors in the world, celebrates the successful completion of the project with NASA JPL / Caltech for the design and production of “Cobra Fiber Positioner”, a two-stage positioning system with rotary motors commissioned for the Subaru telescope in Mauna Kea (Hawaii).

The Cobra system is a mechanism that can position an optical fiber to an accuracy of 5 μm and double the torque compared to traditional DC micro motre.

This technology could be used for applications that require a nanometric positioning of small objects within a small circular area, such as in medical lasers or scanning systems.

Features: cobra-fibra_positioner

Unique and patented piezoelectric rotary technology for PFS application with operating voltage of only 10V and life> 400 of cycles.
Patented and incorporated drive electronics.
Actuator size of only 8mm and fiber coverage radius of 9.5mm
5 μm fiber positioning with inclination <0.3 degrees and defocus <25 μm.
Possibility to maintain the position without power and without play.
Ability to effectively converge in target locations.
Quality guarantee and 100% test on the line to verify all critical specifications.
A highly qualified and experienced micro-mechatronic production staff.

This project, the result of 18 months of research and development, demonstrates the quality and production efficiency of the New Scale Technologies team, and is an example of the customization service that they are able to offer starting from an initial feasibility study to learn whether the project is feasible.
