They also emphasize stress-aware assembly, dynamic simulations for moving components, thermal matching for extreme temperatures, and a specialized material system (Invar or Super Invar with non-magnetic stainless steel and high-elasticity aperture blades such as beryllium) to ensure imaging stability.
