This paper introduces architectures for a large aperture telescope for space astronomy using a Fresnel optic as the primary. Systems built around Fresnel optics hold the possibility of drastically reducing mission costs. The use of a Fresnel optic allows a light weight primary lens which results in lighter systems, which in turn can be flown on smaller, less expensive launchers. Costs are also reduced in the manufacture of the primary lens. The performance of the telescope was given and the tolerancing of the system discussed. The key issue of mitigation of the intrinsic chromatic aberration is discussed in detail. It was shown that architectures based on Fresnel optics can be considered viable and should be considered in the technology selection for future missions.
