Deformable Mirrors
Description
A Missile Defense Agency-funded company developing the next generation of deformable mirror systems hopes to become known as the supplier of the products because its are more precise, more versatile, stronger, and faster than those currently available. One reason why officials at Optical Physics Company (OPC; Calabasas, CA) believe they will succeed is because their mirror’s design significantly minimizes the unwanted surface distortion caused by the intense heat generated when exposed to high-energy laser radiation. Therefore, the mirror can direct high-energy lasers more precisely on target and for longer periods of time than other mirrors used now. The ability to avoid distortion caused by thermal ripple attracted the attention of MDA, which awarded the company a $1 million SBIR Phase II contract in 2007. The agency believes the mirror could be used in military high-energy laser programs. The Phase II funding helped OPC produce and test a 10-centimeterdiameter mirror. The company is expecting to receive add-on funding to build a 30-centimeter device, and is partnering with Lockheed Martin on a highenergy laser program.

Frequently Asked Questions
OPC's deformable mirror system is more precise, versatile, stronger, and faster than those currently available. Its design significantly minimizes unwanted surface distortion caused by intense heat generated by high-energy laser radiation.
A deformable mirror system is a type of mirror that can adjust its shape to correct for distortions caused by high-energy laser radiation.
The advantage of OPC's deformable mirror system is that it can direct high-energy lasers more precisely on target and for longer periods of time than other mirrors used now.
OPC's actuators can move over a range of up to 15 microns, as opposed to 6 or 8 microns for competing actuators.
The Missile Defense Agency has awarded OPC a $1 million SBIR Phase II contract in 2007 for their deformable mirror system.
