Glass selection tends to be both a science and an art. It is the intent of this paper to remove the k(\HAIW
"mystique" surrounding glass selection, primarily based on the chromatic properties of the glass, .eXIbd<C
and to show via careful parametric analyses how we can optimally select glasses for lenses of [?W3XUJ,Y
different f/numbers, spectral bands, and performance requirements. The important roles of m&,d8Gss^
refractive index and Abbe number as well as partial dispersion will be considered. Using the /'E+(Y&:J
SCHOTT glass map, six separate and identifiable regions along with glasses within each region %kNkDI
will be discussed. The goal for this paper is to make glass selection easier to understand.
