Abstract

Large spherical balloons are a promising new option for deploying extremely large, yet light-weight mirrors for stratospheric and space-based applications. However, their lack of a rigid, precise structure presents a unique challenge for optically correcting nonspherical distortions, particularly at shorter wavelengths. In this paper, we present the design and characterization of a lab prototype for a 10-m aperture telescope for observing the water vapor emission line at 538 mum (557 GHz), as well as considerations for future flight-worthy versions.
