Abstract
This paper deals with the predesign of a two-element objective for the infrared spectrum. The design procedure is based on Warren Smith's MOE (Modern Optical Engineering), Third Edition, and illustrates the wealth of information and practical guidance that is available in this classic work. We find the choice of the basic configuration and follow the procedure for minimizing the aberrations through lens-bending, aspherizing, and the use of a diffractive surface. All this is achieved without the use of a computer. The results will then be applied to quickly computer-optimize the system after adding a proper thickness to the elements and a reasonable field of view.
