Abstract

Interest continues in dual waveband and wide waveband optical systems operating in the 3 -12.5 micron spectral region. In some cases, mirror optics will be preferred, in particular where large apertures are involved, precluding the use of refracting materials due to limitations on size. For other applications, catadioptric designs will offer the optimum solution. These approaches may not however, be able to satisfy every requirement. It is necessary therefore to consider design solutions using only refractive optics. A study has been undertaken to explore a range of optical material combinations that aim to provide chromatic correction over this large spectral waveband. Initially, candidate infra red transmitting materials were reviewed and the reliability of their optical and physical properties considered. A representative group of preferred materials was selected. Thin lens calculations were then performed to achieve common focus at several wavelengths, for different material combinations. Focal shift as a function of temperature was also modelled. The most promising combinations were then converted into thick lens design solutions. The performance of these solutions is presented. Apart from design .considerations, the practical suitability of the candidate materials for lens systems is discussed.
