Glass selection tends to be both a science and an art. It is the intent of this paper to remove the f`)*bx
"mystique" surrounding glass selection, primarily based on the chromatic properties of the glass, )8!*,e=4
and to show via careful parametric analyses how we can optimally select glasses for lenses of 6e8 gFQ"w2
different f/numbers, spectral bands, and performance requirements. The important roles of :(\JY?+w
refractive index and Abbe number as well as partial dispersion will be considered. Using the @QMy!y_K~m
SCHOTT glass map, six separate and identifiable regions along with glasses within each region ,+ 5:}hR+
will be discussed. The goal for this paper is to make glass selection easier to understand.
