Glass selection tends to be both a science and an art. It is the intent of this paper to remove the u.!Pda
"mystique" surrounding glass selection, primarily based on the chromatic properties of the glass, ^'FY!^dE
and to show via careful parametric analyses how we can optimally select glasses for lenses of _/MKU!\l
different f/numbers, spectral bands, and performance requirements. The important roles of H%])>
refractive index and Abbe number as well as partial dispersion will be considered. Using the z
^a,7}4
SCHOTT glass map, six separate and identifiable regions along with glasses within each region oPWvZI(\&
will be discussed. The goal for this paper is to make glass selection easier to understand.
