Paper Abstract

It has become traditional[1,2] at these International Lens Design Conferences to pose a problem for designers to tackle, on their own before the conference and during the conference using available computer facilities. The problems provide amusement and challenge to the participants, but in addition, discussion and comparison of the designs submitted can teach us about different approaches to the design process. In the recent past, progress has been made in several areas affecting design. New systematic approaches to the design process are being proposed. Technolo(xies such as the use of aspherics and gradient index materials are now available to the designer, requiring new approaches to optical system design. For the problem this time. the participant.: were asked to make all decisions about design form. They were asked how the designs were initiated and what factors were important to the design form decision. A first-order problem was posed with no suggested starting solution and no performance requirement. It was intended to be a problem with no well known "best" solution -- something sufficiently out of the ordinary to pique interest and encourage original thought. The participants were asked to design a finite conjugate lens with pupil-image symmetry: a reversible lens. This paper is intended to introduce the problem and, of course, to present the solutions submitted before the conference. Forty solutions were received from twenty-eight designers from eight countries, representing a wide variety of approaches to the problem. Two companion papers can be found elsewhere in this Proceedings: Walther[3] discusses the fundamental performance limitations of symmetric reversible systems and Hopkins presents his personal approach to the problem as a designer with many years of experience.
