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
