Glass selection tends to be both a science and an art. It is the intent of this paper to remove the xX.kKEo"d
"mystique" surrounding glass selection, primarily based on the chromatic properties of the glass, .z[#j]k
and to show via careful parametric analyses how we can optimally select glasses for lenses of RQ;w$I\
different f/numbers, spectral bands, and performance requirements. The important roles of aC94g7)`
refractive index and Abbe number as well as partial dispersion will be considered. Using the [ J4n%
SCHOTT glass map, six separate and identifiable regions along with glasses within each region @% jY
will be discussed. The goal for this paper is to make glass selection easier to understand.
