Glass selection tends to be both a science and an art. It is the intent of this paper to remove the >k}Kf1I
"mystique" surrounding glass selection, primarily based on the chromatic properties of the glass, 5! 6iAS+I
and to show via careful parametric analyses how we can optimally select glasses for lenses of ZM =eiJZ
different f/numbers, spectral bands, and performance requirements. The important roles of 0J5$
Yw1'F
refractive index and Abbe number as well as partial dispersion will be considered. Using the 5VN~?# K
SCHOTT glass map, six separate and identifiable regions along with glasses within each region bg|=)sw4
will be discussed. The goal for this paper is to make glass selection easier to understand.
