Lightweight Silicon Carbide Replicated Optics


Silicon-carbide mirrors are becoming a highly considered alternative for stressing optical applications over more conventional glass, aluminum and beryllium approaches.  Of particular interest are 1+ meter class space applications that would benefit from active figure control and where manufacturability is a significant driver.  AOA-Xinetics has developed a novel design and manufacturing process for lightweight silicon-carbide replicated mirrors possessing actuators that offer high order figure control.  This talk will present an overview of the technology, the manufacturing process and design capabilities that support current and future applications.  Some examples of delivered optical components and full multi-segmented primaries will be presented.
