What is the outgassing rate of the fiber coating (e.g., Polyimide) in Ultra-High Vacuum (UHV) environments? Does it meet aerospace-grade standards?

OFSCN® SM Polyimide Optical Fiber is known for its excellent thermal stability, with an operating temperature range of -200℃ to 350℃ (continuous) and -270℃ to 350℃ (short-term). Polyimide coatings are generally characterized by low outgassing properties and high chemical inertness, which makes them suitable for applications in vacuum environments.

While specific outgassing rates vary depending on the exact polyimide formulation, curing process, and testing standards (e.g., ASTM E595 for aerospace outgassing), polyimide is a commonly chosen material for high-performance and vacuum applications due to its inherent properties. For detailed aerospace-grade certification or specific outgassing rate data, additional testing documentation would be required.
