Glass selection tends to be both a science and an art. It is the intent of this paper to remove the 4e%8D`/=M
"mystique" surrounding glass selection, primarily based on the chromatic properties of the glass, (:?&G9k
"
and to show via careful parametric analyses how we can optimally select glasses for lenses of oXc/#{NC
different f/numbers, spectral bands, and performance requirements. The important roles of cqQRU
refractive index and Abbe number as well as partial dispersion will be considered. Using the QJ<[Zx
SCHOTT glass map, six separate and identifiable regions along with glasses within each region 2:J,2=%
will be discussed. The goal for this paper is to make glass selection easier to understand.
