Glass selection tends to be both a science and an art. It is the intent of this paper to remove the ^__';! e
"mystique" surrounding glass selection, primarily based on the chromatic properties of the glass, nM#/uuRl|
and to show via careful parametric analyses how we can optimally select glasses for lenses of 2PZ#w(An&
different f/numbers, spectral bands, and performance requirements. The important roles of r`-=<@[
refractive index and Abbe number as well as partial dispersion will be considered. Using the Wz{,N07Q#{
SCHOTT glass map, six separate and identifiable regions along with glasses within each region N_L~oX_
will be discussed. The goal for this paper is to make glass selection easier to understand.
