Glass selection tends to be both a science and an art. It is the intent of this paper to remove the e
,k,L
"mystique" surrounding glass selection, primarily based on the chromatic properties of the glass, <<@$0RW
and to show via careful parametric analyses how we can optimally select glasses for lenses of "<t/*$42
different f/numbers, spectral bands, and performance requirements. The important roles of 89U<9j
refractive index and Abbe number as well as partial dispersion will be considered. Using the %=S~[&8C
SCHOTT glass map, six separate and identifiable regions along with glasses within each region |\*7J!Liv
will be discussed. The goal for this paper is to make glass selection easier to understand.
