ALLVAR wins NASA SBIR Phase II award

ALLVAR alloys has been awarded a NASA Small Business Innovative Research Phase II grant for “Ultra-stable ALLVAR Alloy Strut Development for Space Telescopes.”

This NASA SBIR Phase II proposal was in response to the need for Ultra-Stable Telescope Structures and is designed to evaluate ALLVAR Alloys for their potential as metering and support structures for optics that are critical to NASA’s future missions. Telescopes used for astrophysics, exoplanet, and planetary studies require picometer stability over several minutes to hours. Building large support structures with picometer level stability is a challenge with currently available materials due to their brittle nature in the case of Zerodur and ULE or their requirement to have tight thermal control in the case of SiC or carbon fiber composites. ALLVAR Alloys offer a new material solution for thermally stable structures. They exhibit negative thermal expansion and can compensate for the positive thermal expansion of other materials to stabilize a telescope.
