Paper Abstract

Studies conducted during the past 2 years at Itek have identified many of the major system level considerations leading to the design of a diffraction limited 3-m-aperture astronomical telescope for NASA's proposed large space telescope (LST) program. Studies in the following areas are described: telescope configuration; primary mirror and system focal ratios; primary mirror configuration, materials, and mount; secondary mirror mount; telescope structural materials; operating temperatures and thermal control; fine pointing; and system maintainability. A tentative system level wave-front error budget is presented for a 3-m-aperture diffraction limited LST, and the practicality of achieving this goal in an opera-tional system late in this decade is commented on.
