Paper Abstract

Due to the increasing environmental limitations imposed on the chemical materials used in optical glass production, there is now an economic desire to minimize the number of glasses used in lens design. This paper presents the results of a study to create a glass listing that contains the minimum number of glasses needed for most lens designs. A double Gauss lens is used in the glass selection process. As part of this study, the relationship between the error function and the number of glasses chosen, as defined by a glass-count study, is found, as is the relationship between the error function and the location of a particular glass, as defined by glass-range study. Three lens libraries were studied using the global optimization method, and the most frequently chosen glasses were then compiled into the recommended glass listing according to the glass-count and glass-range studies. A recommended glass listing with nine glasses constructed from this study is presented.
