This study evaluates the performance of vertically fused face sheet mirrors used in adaptive optical systems that are subjected to high thermal irradiance. A one meter diameter by 20 mm thick segmented, low expansion glass face sheet was fabricated from different boules of glass and characterized for material properties. The study includes thermal irradiation testing using interferometric measurements and detailed analytical modeling.
