Glass selection tends to be both a science and an art. It is the intent of this paper to remove the q1L>nvE
"mystique" surrounding glass selection, primarily based on the chromatic properties of the glass, @8m%*pBg
and to show via careful parametric analyses how we can optimally select glasses for lenses of #W/Ch"Kv
different f/numbers, spectral bands, and performance requirements. The important roles of +RM!j9Rq
refractive index and Abbe number as well as partial dispersion will be considered. Using the +924_,zF
SCHOTT glass map, six separate and identifiable regions along with glasses within each region E A55!
will be discussed. The goal for this paper is to make glass selection easier to understand.
