Paper Abstract

Free-space optical communications terminals frequently rely on optical telescopes to enhance the transmitted and received efficiency of the communication system. We have designed and patented a suite of monolithic optical telescope systems, fabricated from a single piece of transparent material. In small sizes (5 to 15 cm apertures) these designs hold promise for reducing flight terminal mass and volume, reducing risks associated with telescope alignment, and reducing costs of flight optical terminals when produced in volume. This paper presents variations of optical designs and compares their characteristics, and fabrication tolerances. Results of a prototyping effort demonstrate the feasibility of producing these elements using modern fabrication techniques.
