With more rapid, affordable access to space and the emerging availability of large-volume fairings, owners and users of current and future space-based optical systems are desiring large-aperture or segmented-aperture primary mirrors for their missions. This demand is driving the need for new approaches to optical component fabrication to produce mirrors and mirror segments that are more cost-efficient with faster manufacturing lead times than traditional optical components. Harris Corporation is executing a mirror development strategy called Advanced Mirror Construction (AMC) to meet this need while still meeting the challenging requirements of space-based optics. A key component of this strategy is the utilization of replication to produce precision lightweight mirror components. We present the motivation and initial results for lightweight replicated, ultra-stable mirrors and mirror segments as well as other key elements of the AMC strategy.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for most presentations.
