Glass selection tends to be both a science and an art. It is the intent of this paper to remove the H7n>Vx:L-
"mystique" surrounding glass selection, primarily based on the chromatic properties of the glass, %tGO?JMkd
and to show via careful parametric analyses how we can optimally select glasses for lenses of wi=v}R_
different f/numbers, spectral bands, and performance requirements. The important roles of gwMNYMI
refractive index and Abbe number as well as partial dispersion will be considered. Using the P=
NDS2
SCHOTT glass map, six separate and identifiable regions along with glasses within each region lL3U8}vn
will be discussed. The goal for this paper is to make glass selection easier to understand.
