Deformable Mirror Technology Aid

Photonics Spectra
Jan 2011
Microelectromechanical systems (MEMS)-based deformable mirror provider Boston Micromachines Corp. (BMC) of Cambridge, Mass., announced that it has signed a consulting agreement with Bridger Photonics Inc. of Bozeman, Mont., to quantitatively assess a new MEMS membrane deformable mirror design using BMC’s facilities. Bridger Photonics received a Small Business Technology Transfer grant from the National Science Foundation to develop a commercial prototype of an aberration-compensated focus control device. Based on MEMS technology, the device will allow the user to deflect a deformable membrane mirror in a controlled manner to select a desired focal length. It will feature active control of low-order aberrations.



GLOSSARY
aberration
A departure from ideal paraxial imaging behavior. The distortion of an optical field wavefront as it is propagated through the elements of an optical system. The field distortion is due to the interaction of the wavefront with ideal components and therefore a result of optical component behavior.
