Glass selection tends to be both a science and an art. It is the intent of this paper to remove the -I -wdyDr
"mystique" surrounding glass selection, primarily based on the chromatic properties of the glass, "783F:mPh
and to show via careful parametric analyses how we can optimally select glasses for lenses of }5~ ;jN=k
different f/numbers, spectral bands, and performance requirements. The important roles of 8) i\d`
refractive index and Abbe number as well as partial dispersion will be considered. Using the ?mV[TM{p
SCHOTT glass map, six separate and identifiable regions along with glasses within each region m'pihFR:f
will be discussed. The goal for this paper is to make glass selection easier to understand.
