The Miniaturized Ultraviolet Imager, or MUVI for short is a compact wide field UV imager currently in development at UC Berkeley Space Sciences Laboratory and Cal Poly, San Luis Obispo. MUVI is designed to fit in a 2U CubeSat form factor and provide wide field, high resolution images of the ionosphere at far ultraviolet wavelengths. This paper details the design and analyses of MUVI’s primary structure and detector mounting flexure. The team has developed a novel approach for replicating the boundary conditions of a CubeSat dispenser for on-ground vibration testing. Design challenges, including accommodation of a deployable optic and meeting volume constraints of a 2U envelope, are discussed in detail. Existing prototype subassemblies and mass models were integrated and aligned to the structure prior to environmental testing.
