Optical and photonics systems are extremely sensitive to dimensional changes. Even minimal thermal expansion can cause misalignment, image distortion, or signal loss. Super Invar 32-5 has become a preferred material in this field due to its near-zero thermal expansion and excellent long-term stability. Telescopes, laser systems, and precision optical mounts often operate in environ... https://www.bhansaliaeroalloys.com/super-invar-32-5/
