Glass selection tends to be both a science and an art. It is the intent of this paper to remove the '16b2n+F@#
"mystique" surrounding glass selection, primarily based on the chromatic properties of the glass, wi6
~}~%
and to show via careful parametric analyses how we can optimally select glasses for lenses of @r/nF5
different f/numbers, spectral bands, and performance requirements. The important roles of b}TS0+TF
refractive index and Abbe number as well as partial dispersion will be considered. Using the HRfYl,S,
SCHOTT glass map, six separate and identifiable regions along with glasses within each region _>X+ZlpU:
will be discussed. The goal for this paper is to make glass selection easier to understand.
