As leader in the design, manufacturing, and testing of electro-optical systems for space applications, Lockheed Missiles and Space Company is committed to the development of technology driven and competitively priced high quality products. In view of this commitment of improving quality and reducing cost, several designs for unobscured, off-axis, high performance, reflective optical telescopes for IR applications have been developed. The designs presented in this paper have been modeled and analyzed using state-of-the-art optical and mechanical design computer programs to determine their effectiveness in achieving very good optical characteristics, light weight, and low manufacturing cost. In particular a three mirror system is described which is capable of optical performance close to diffraction limit over a circular field of view of 20 degrees at f/4.
