Abstract

The Fabrication of Affordable Aspheric Mirrors by Electroforming (FAAME) program seeks to lower the cost of aspheric mirrors by developing electroforming processes suitable for optical-quality electroforms. To achieve this goal, two major areas of improvement were pursued: optimizing the electroforming process and utilizing a multi-generational approach. To improve the process, we studied electroforming variables, identifying key factors that affect an electroform's optical quality. Once the factors were identified, the electroforming process was refined, producing mirrors that met the quality goal of 1/4 wave in the infrared. We drew all of this experience together to demonstrate replication of a wildly aspheric mirror for use in a Trans-Atmospheric Interceptor (TAI).
