Boston Micromachines New Deformable Mirror Controller Enables Researchers to Quickly Integrate Adaptive Optics Into Laser Shaping Applications
New Deformable Mirror Controller Enables Low Cost Adaptive Optics Proof-of-Concept Experiments

Cambridge, Mass., June 1, 2009 – Boston Micromachines Corporation, a leading provider of MEMS-based deformable mirror (DM) products for adaptive optics systems, today announced a new high speed, high precision controller for its Mini-DM.  This new controller provides increased resolution and speed and has been engineered in a package five times smaller than the previous version. The Mini-DM’s low cost, small size and high functionality enable researchers to accomplish adaptive optics proof-of-concept experiments for laser beam shaping.

“The Mini-DM Controller is an easy and cost effective tool for proof-of-concept research,” said Paul Bierden, president and CEO of Boston Micromachines, “as well as applications where compact size and low cost are paramount to successful implementation.”
The new controller, which enhances Boston Micromachines’ Mini-DM, has been improved to provide 14 bit resolution in position control at greater than an 8 kHz frame rate.
The Mini-DM is also used to improve resolution in microscopes, telescopes, and ophthalmic instruments.  It is ideal for laboratory-scale adaptive optics and proof-of-concept wavefront control in microscopy and vision science research where imaging instruments often suffer from resolution limitations.  The Mini-DM is currently being used in vision science by researchers studying glaucoma, diabetic retinopathy, and age-related macular degeneration. In microscopy, the Mini-DM’s ability to actively correct for aberrations helps researchers extract vital information from biological specimens. 

The new Mini-DM Controller will be on display at Boston Micromachines’ Booth 1612 at PhotonXpo–The Exhibit at CLEO in the Baltimore Convention Center Tuesday, June 2nd through Thursday June 4th.

About the Mini-DM
The Mini-DM is an advanced wavefront control device that consists of a mirror membrane supported by an underlying actuator array.  Each actuator in the array can be individually deflected by electrostatic actuation to achieve the desired pattern of deformation. Unlike other technologies such as electromagnetic and piezoelectric mirrors, electrostatic actuation ensures mirror deformation without hysteresis.

The compact and affordable Mini-DM is ideal for laboratory-scale adaptive optics and low-order wavefront control.  This turnkey system comes complete with a USB controller, software and a gimbal mount for easy installation
