A method for correcting spherical aberration and coma in fast two-element objectives using high-index materials is discussed. It involves use of an aplanatic lens with a single lens having a minimum spherical aberration and no coma. The method deals only with monochromatic designs. It can be effective in designing high-aperture aplanatic IR objectives. Optical data and performance characteristics of germanium and silicon two-lens systems designed by the proposed method are given.
