Deformable Mirror 492-3.5
Description
The 492-DM deformable mirrors: A high performance wavefront corrector for astronomy and imaging applications. The 492-DM is an enabling component for precise, high speed, high resolution wavefront control. With 492 actuators controlled to under 1 nm of precision and no hysteresis, this system is ideal for demanding applications in astronomy and next-generation imaging. The high-speed electronics driver is capable of 60 kHz frame rate and 14 bit step resolution. As an alternative to the popular Kilo-DM deformable mirror, the 492-DM can be used at a lower cost with powerful results.

Features
MEMS deformable mirrors (DM) are currently the most commonly used in many adaptive optics applications given their versatility, maturity of technology, and the high resolution wavefront correction capabilities. Using advanced, inexpensive manufacturing technology, MEMS DMs’ performance strengths are inherent to micromachining:
1. Large actuator 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.
