Glass selection tends to be both a science and an art. It is the intent of this paper to remove the E?]$Y[KJKs
"mystique" surrounding glass selection, primarily based on the chromatic properties of the glass, m+M^we*R
and to show via careful parametric analyses how we can optimally select glasses for lenses of |21V OPBS
different f/numbers, spectral bands, and performance requirements. The important roles of += W(c8~P
refractive index and Abbe number as well as partial dispersion will be considered. Using the @0@WklAJA
SCHOTT glass map, six separate and identifiable regions along with glasses within each region Eq_@ xT0>
will be discussed. The goal for this paper is to make glass selection easier to understand.
