Deformable Mirror HEX-3K
Description
The +K-DM Family deformable mirrors: High spatial-resolution wavefront correctors for next generation applications in astronomy and laser communications. Boston Micromachines Corporation is leading the industry in high actuator‐count MEMS deformable mirror technology. These mirrors are fielded at prominent astronomical facilities around the world to improve wavefront correction capabilities, enabling cutting edge science. The 4K‐DM deformable mirror is currently being installed on the Gemini Planet Imager instrument and our 3KDM is included in the design for multiple space telescope concepts. Finally, the 2K‐DM is currently installed as an enabling component in the Subaru Coronagraph Extreme Adaptive Optics (SCExAO) Instrument and has been on‐sky multiple times.

Features
MEMS deformable mirrors are the most commonly used architecture in many AO applications given their versatility, maturity of technology, and the high resolution wavefront correction capabilities with sub-nm step size. Using advanced, inexpensive manufacturing technology, MEMS DMs’ performance strengths are inherent to micromachining:
1. Large arrays create high resolution wavefront correction.
2. Advanced microstructures allow minimal influence between adjacent actuators for high spatial frequency surfaces
3. Optimized design enables rapid wavefront shaping for high speed applications.
