Glass selection tends to be both a science and an art. It is the intent of this paper to remove the E`int?C!
"mystique" surrounding glass selection, primarily based on the chromatic properties of the glass, Kt@M)#
and to show via careful parametric analyses how we can optimally select glasses for lenses of l^GP3S
different f/numbers, spectral bands, and performance requirements. The important roles of }%b;vzkG5
refractive index and Abbe number as well as partial dispersion will be considered. Using the :y*NM,s
SCHOTT glass map, six separate and identifiable regions along with glasses within each region Y8M]Lwj
will be discussed. The goal for this paper is to make glass selection easier to understand.
