The SST program has developed the technology for large, curved focal surface array sensors which enable an innovative Mersenne-Schmidt telescope design.  This design allows for a short focal length, wide field of view and a compact optical train which allow for rapid step-and-settle motions to be executed. The SST mirrors are some of the steepest aspherical curvatures ever to be polished and allow the telescope to have the fastest optics of this aperture class.
