Abstract

Harris designed and manufactured a 1.5 meter diameter Corning ULE mirror assembly that is 1/3 scale of a 4 meter monolithic mirror design for NASA’s Advanced Mirror Technology Development program in order to mature the lightweight mirror technology needed for a large space qualified UVOIR mirror so that a viable mission can be considered for the 2020 Decadal review. This mirror assembly was examined using X-rays computer tomography for cross sectional views to detect any manufacturing defects. The mirror assembly was tested for thermal stability at room temperature down to 240 degrees Kelvin, followed with modal test in order to correlate to FEM models.
