Glass selection tends to be both a science and an art. It is the intent of this paper to remove the O.?q8T)n82
"mystique" surrounding glass selection, primarily based on the chromatic properties of the glass, a ]x\ e{
and to show via careful parametric analyses how we can optimally select glasses for lenses of HmpV;
<t3
different f/numbers, spectral bands, and performance requirements. The important roles of "'c
=(P
refractive index and Abbe number as well as partial dispersion will be considered. Using the 8 =3$U+
SCHOTT glass map, six separate and identifiable regions along with glasses within each region EkP(] F
will be discussed. The goal for this paper is to make glass selection easier to understand.
