Abstract

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.
