The design of a unique, self deployable light shade is discussed. This shade was specifically designed for the Small Astronomy Satellite (SAS-B), of the National Aeronautics and Space Administration. While there are numerous boundary conditions imposed upon the design of the light shade by the physical limitations of the SAS-B satellite and the payload envelope, the basic design concepts can be utilized for other applications. A number of candidate light shade designs are presented with a discussion of the functional concepts. The final design selection was predicated upon its photometric properties, e.g., very high attenuation of scattered light, its rugged, light weight physical properties, and its compressibility or fold-ability along with its self deployment features within the restrictions of the satellite payload envelope.
