Description
The astatic electrical actuaor µAME12-SPACE provides bidirectionnal force of high precision and
enable coupling with optic without any static friction.
Its design, patented by ISP System, is based on robuste and reliable technologies.
Non contractual photo
The principle of force generation is based on the imbalance of a spring system:
At state "0", the pull and push springs are balanced.
The action of a screw-nut system changes the length of the thrust springs through a rod.
The motion is powered with a stepping motor. It can generate a stable and accurate driven strain, even
power off thanks to its irreversible mechanical.
Pull and push forces are generated on the travel direction of the rod which activate the springs
The floating head enable the coupling with optical membrane: this technology allows angular and radial
misalignments without any static friction.
Features can be modified to fit customer’s requirements.
Applications
The actuator µAME 12-Space has been developped to motorize active optics intended in particular for
the correction of wavefront.
Compatible to aerospace constraints.
This version is specifically adapted to be integrated to the mirror ACMAS (*)
