The first Optical Reflector Materials Experiment (ORMatE-I) is on-board MISSE-6. The follow-on experiment, ORMatE-II, is part of MISSE-7. Both these projects are a collaborative effort among The Aerospace Corporation, the US Naval Research Laboratory (NRL), and the Air Force Research Laboratory Materials Directorate (AFRL/ML). ORMatE-I is a study of optically reflective materials focused on SiC for use as a lightweight mirror substrate. Several types of SiC material grown by different methods and vendors are included as well as diverse coating materials and deposition techniques. Advanced glass substrate technologies, like ULE and corrugated borosilicate, are also on-board. Additional SiC and composite materials will be evaluated on ORMatE-II along with silver mirrors deposited by various means. A description of both experiment suites and a summary of the pre-flight optical characterization will be presented.
