Abstract

Wolter-I Optics for SmallSat Astronomy Mission (WOSAM) are a highly adaptable option for SmallSat missions for a number of astronomical uses. These compact Wolter-I optics with focal lengths on the order of 0.5 - 1 m are able to fit within strict mass and volume constraints and can be designed to fit the scientific requirements of exoplanet, solar, and lunar missions. In order to maximize Effective Area the telescope’s collecting area, graze angle, and vignetting need to be balanced. These factors are primarily affected by the optics’ focal length, outer diameter, shell length, and shell spacing. We show the modeling results of three SmallSat missions, the SmallSat Exosphere Explorer of hot Jupiters (SEEJ), the SmallSat Solar Axion and Activity X-ray Imager (SSAXI), and the Lunar X-ray Imaging Spectrometer (LuXIS). These missions have a range of Effective Area, Energy band, and Field of View requirements that can all be met with WOSAM telescopes.
