Boston Micromachines, Bridger Photonics Sign Consulting Deal
Dec 2010
CAMBRIDGE, Mass., Dec. 8, 2010 — Boston Micromachines Corp. (BMC) announced Monday that it has signed a consulting agreement with Bridger Photonics Inc. to quantitatively assess a new MEMS membrane deformable mirror design using BMC’s facilities.

“We recognized that Boston Micromachines is a world leader in deformable MEMS membranes. The two companies’ technologies complement one another very well, so the fit is natural,” said Peter Roos, president and CEO of Bridger Photonics. “We are excited to capitalize on BMC’s proven expertise and knowledge in the field of deformable mirrors.”

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.

The technology enables next-generation biomedical imaging devices for microscopy applications to focus control and aberration correction in simple, compact and low-cost sensors.

“Progress in deformable mirror (DM) technology has inspired innovative researchers to make advances in fields such as astronomy, microscopy, retinal imaging and laser communications,” said Paul Bierden, BMC president and CEO. “We are pleased to provide our extensive DM technology knowledge to Bridger Photonics to support its efforts to expand the role of MEMS DM technology in wavefront correction for scientific advancement.”

Boston Micromachines provides MEMS-based DM products for adaptive optics systems.

adaptive optics
Optical components or assemblies whose performance is monitored and controlled so as to compensate for aberrations, static or dynamic perturbations such as thermal, mechanical and acoustical disturbances, or to adapt to changing conditions, needs or missions. The most familiar example is the "rubber mirror,'' whose surface shape, and thus reflective qualities, can be controlled by electromechanical means. See also active optics; phase conjugation.
The scientific observation of celestial radiation that has reached the vicinity of Earth, and the interpretation of these observations to determine the characteristics of the extraterrestrial bodies and phenomena that have emitted the radiation.
Any bending of a wave of radiation away from its expected path, as, for example, by diffraction or by a magnetic field.
laser communications
A smooth, highly polished surface, for reflecting light, that may be plane or curved if wanting to focus and or magnify the image formed by the mirror. The actual reflecting surface is usually a thin coating of silver or aluminum on glass.
