Glass selection tends to be both a science and an art. It is the intent of this paper to remove the /4Ud6gscf
"mystique" surrounding glass selection, primarily based on the chromatic properties of the glass, .[mI9dc
and to show via careful parametric analyses how we can optimally select glasses for lenses of Z:>)5Z{'
different f/numbers, spectral bands, and performance requirements. The important roles of UnTnc6Bo7W
refractive index and Abbe number as well as partial dispersion will be considered. Using the in}d(%3h
SCHOTT glass map, six separate and identifiable regions along with glasses within each region yN-o?[o
will be discussed. The goal for this paper is to make glass selection easier to understand.
