Glass selection tends to be both a science and an art. It is the intent of this paper to remove the
IZ-1c1
"mystique" surrounding glass selection, primarily based on the chromatic properties of the glass, sRR( `0Zp
and to show via careful parametric analyses how we can optimally select glasses for lenses of `,*3[
different f/numbers, spectral bands, and performance requirements. The important roles of F@jZ ho
refractive index and Abbe number as well as partial dispersion will be considered. Using the PcMD])Z{G
SCHOTT glass map, six separate and identifiable regions along with glasses within each region &ee~p&S,>
will be discussed. The goal for this paper is to make glass selection easier to understand.
