Open-Loop Calibration


An enhancement over simple voltage control

For users who prefer to operate our mirror in deflection-space over voltage-space, we offer an upgrade to our basic control software. This option simplifies the use of the mirror in open loop situations where closed-loop operation is not desired or orthogonal shapes need to be generated. This can be purchased with your mirror or any time thereafter, to enhance your DM control experience. This capability can be implemented in your existing software setup using any of the already-available software drivers included with your Multi- or Mini-DM.


Hermetic Seal


Improved Isolation from Harsh Environments

For users who would like an added level of isolation from the elements, we offer hermetical sealing on select models of our deformable mirrors. These mirrors meet the requirements of the MIL-STD-883 specification. Prices vary based on product. Please contact us for more details.

   The Kilo-DM: An enabling component for precise, high speed, high resolution wavefront control. The Kilo-DM was originally developed for a DARPA coherent laser communication project and is currently used by the European Southern Observatory, NASA's Terrestrial Planet Finder, the Subaru Observatory, and various defense agencies. ​ Scroll down for more information on options.

MEMS Deformable Mirrors 

MEMS Deformable mirrors are currently most commonly used in many AO applications given their versatility, the maturity of the technology, and their high-resolution wavefront correction capabilities. Using advanced, inexpensive manufacturing technology, MEMS DMs performance strengths are inherent to micromachining:

​   -Large actuator arrays compensate for high resolution wavefront errors
   -Advanced microstructures allow minimal influence between adjacent actuators for high spatial frequency wavefronts
​   -Optimized design enables rapid wavefront shaping for high speed applications

   The S-Driver: Advanced solution for high speed and low price. Ideal for increased depth imaging through turbid media. Pair either the 492-DM or Kilo-DM with the high-speed S-Driver for fast and precise wavefront control, achieving speeds up to 60 kHz. Scroll down for more information on options.


   The 492-DM: A high performance wavefront corrector ideal for demanding applications in astronomy and laser communications.  As an alternative to the popular Kilo-DM, the 492-DM can be used at a lower cost with powerful results.
