Abstract
Space Grade Spectralon® (SGS) has become a standard tool for on-board satellite instrument calibration and verification schemes. This paper provides an overview of the development process, a comprehensive history of the development of SGS, its space qualification, and characterization and degradation studies performed to date. SGS material properties and failure mechanisms are also discussed. The current state of the art and best-practice use of sintered PTFE materials in space is described, including critical findings that drive methodology and design guidelines. Also discussed are practical lessons-learned from past implementations of Spectralon® in space and how that impacts the rationale behind the use of fully-pedigreed SGS vs. vacuum-baked Optical Grade Spectralon® for various applications.
