The use of epoxies in space-based instruments is often unavoidable in situations where the bonding of dissimilar materials such as glass and metal is required. Epoxies in vacuum can outgas and release contaminants that then contaminate optical surfaces, this can lead to instrument degradation and shorter operational lifetimes. Epoxies can also be incompatible with exposure to chemical environments some space instrumentation may be exposed to. In high power laser instruments such as LIDAR systems where optical components must be securely bonded to metal mounts, the impact of epoxy outgassing can be especially acute. Even with very low outgassing levels, the intense laser can break down the outgassed material and preferentially deposit it on optics that handle high optical power. This laser induced contamination in turn leads to laser induced damage. Alternative bonding methods that avoid introducing additional contaminants could greatly improve reliability and operational lifetime of space instruments.
