Glass selection tends to be both a science and an art. It is the intent of this paper to remove the QK~>KgVi
"mystique" surrounding glass selection, primarily based on the chromatic properties of the glass, OUHd@up@n
and to show via careful parametric analyses how we can optimally select glasses for lenses of .b%mr:nEt7
different f/numbers, spectral bands, and performance requirements. The important roles of F fzY3r+
refractive index and Abbe number as well as partial dispersion will be considered. Using the %D^j7`Z
SCHOTT glass map, six separate and identifiable regions along with glasses within each region ,"5p=JX`
will be discussed. The goal for this paper is to make glass selection easier to understand.
