Description
mu-DM is a versatile, single-piece design, electromagnetic deformable mirror, which can be implemented in an open-loop or along with a wavefront sensor in a closed-loop setting.
mu-DM is a Deformable Mirror (DM) containing 91 electromagnetic actuators organized in a centro-symmetrical pattern. The main highlights of this DM are:
- A high density of actuators
- Embedded electronics, for easier implementation
- A high dynamic range, linearity and stability
