Paper Abstract

Plastic lenses are widely used in visible imaging systems and provide a number of advantages including reduced weight. However, their use in the short-wave infrared (SWIR) has been limited due to the presence of strong material absorption bands occurring at wavelengths above 1 micron. This paper explores the viability of using plastic optics in broadband SWIR imaging applications and the efficacy of using plastic lenses as a method of weight reduction. A design study is presented to reveal combinations of plastic and glass lenses suitable for aberration correction. Weight savings is quantified via a comparison to glass lenses to investigate the trade-off between using lower density plastic materials and the faster F/#s (i.e. larger lenses) required to compensate for the signal loss caused by their absorption.
