Glass selection tends to be both a science and an art. It is the intent of this paper to remove the IDos4nM27]
"mystique" surrounding glass selection, primarily based on the chromatic properties of the glass, Ck %if
and to show via careful parametric analyses how we can optimally select glasses for lenses of Jn | i!
different f/numbers, spectral bands, and performance requirements. The important roles of vV 9vB3K5?
refractive index and Abbe number as well as partial dispersion will be considered. Using the }

SCHOTT glass map, six separate and identifiable regions along with glasses within each region QZ;DZMP
will be discussed. The goal for this paper is to make glass selection easier to understand.
