Abstract
This paper presents a new graphical method for selecting an optimum pair of optical glass and housing materials to simultaneously achromatize and athermalize a multilens system, by use of iterative method. To take into account the lens spacing and housing, we newly quantify the lens powers of the elements by weighting the ratio of the paraxial ray height at each element to them. In addition, we introduce the equivalent single lens and the expanded athermal glass map including a housing material. Even though there is no glass satisfying athermal and achromatic conditions, we can iteratively identify a pair of glass and housing materials by changing the power of equivalent lens.
