Glass selection tends to be both a science and an art. It is the intent of this paper to remove the k*[["u^u]
"mystique" surrounding glass selection, primarily based on the chromatic properties of the glass, m "h{HgJd
and to show via careful parametric analyses how we can optimally select glasses for lenses of {-09,Q4[&
different f/numbers, spectral bands, and performance requirements. The important roles of -: dUD1
refractive index and Abbe number as well as partial dispersion will be considered. Using the ;1A4p `)
SCHOTT glass map, six separate and identifiable regions along with glasses within each region r|:i: ii
will be discussed. The goal for this paper is to make glass selection easier to understand.
