Glass selection tends to be both a science and an art. It is the intent of this paper to remove the HMY@F_qY`u
"mystique" surrounding glass selection, primarily based on the chromatic properties of the glass, #Dfo#]k(
and to show via careful parametric analyses how we can optimally select glasses for lenses of S-#q~X!yJ
different f/numbers, spectral bands, and performance requirements. The important roles of YwcPX`eg
refractive index and Abbe number as well as partial dispersion will be considered. Using the D7"p}PD>~
SCHOTT glass map, six separate and identifiable regions along with glasses within each region /=?ETth @
will be discussed. The goal for this paper is to make glass selection easier to understand.
