Reynard Corporation has developed space optics for satellite imaging, confidential military and aerospace needs, and general R&D programs.
Optical filters and coatings used in space applications pose a unique set of reliability requirements. Typically, materials must exhibit low-outgassing characteristic as defined by NASA Reference Publication 1124; Total Mass Loss (TML) <1.0% and Collected Volatile and Condensable Materials (CVCM) <0.10%. For transmission coatings used in the presence of ionizing radiation at cryogenic temperatures, purity of input materials is of utmost importance to prevent performance degradation. For reflective coatings used in potentially high-fluence ionizing radiation environment, additional considerations are made to select only those materials capable of minimal interaction.
Physical Vapor Deposition (PVD):
Reynard Corporation predominantly employs physical vapor deposition (PVD) methods in our thin-film manufacturing process, and only processes materials capable of meeting the NASA outgassing requirement. For example, silicone materials are strictly prohibited from entering specific vacuum chambers due to their high volatility and contamination risks. By adhering to such strict requirements, we’re able to ensure our customers’ critical space application items are never at risk of spurious contamination.
