Description
The Kilo-DM deformable mirror is an enabling component for precise, high speed, high resolution wavefront control. With 952 actuators controlled to under 1nm of precision and no hysteresis, this system is ideal for demanding applications. The high-speed drive electronics are capable of 60 kHz frame rate and 14 bit step resolution. Originally developed for a DARPA coherent laser communication project, the Kilo-DM deformable mirror is currently used by the European Southern Observatory, the Lick Observatory at Mt. Hamilton, and various defense agencies.

Frequently Asked Questions
The Kilo-DM and the 492-DM are both high performance wavefront correctors for demanding applications, but the 492-DM has 492 actuators controlled to under 1 nm of precision and can be used at a lower cost.
The MEMS deformable mirrors have continuous or segmented surfaces, 492 actuators, zero hysteresis, and a fill factor of over 99%. They also have a sub-nm average step size and stroke of 1.5 μm or 3.5 μm.
The driver interface for the MEMS deformable mirrors is a SFP fiber link connection via PCIe Interface Card, with a 14 bit step resolution and maximum frame rate of 34 kHz / 60 kHz (Low Latency).
The Kilo-DM deformable mirror is used for precise, high speed, high resolution wavefront control in demanding applications such as astronomy and laser communications.
The high-speed drive electronics of the Kilo-DM deformable mirror are capable of 60 kHz frame rate and 14 bit step resolution.
