Glass selection tends to be both a science and an art. It is the intent of this paper to remove the c? 3F9 w#
"mystique" surrounding glass selection, primarily based on the chromatic properties of the glass, :b3l J-dB
and to show via careful parametric analyses how we can optimally select glasses for lenses of fSQ3 :o
different f/numbers, spectral bands, and performance requirements. The important roles of $M8> SLd
refractive index and Abbe number as well as partial dispersion will be considered. Using the QVZ6;/
SCHOTT glass map, six separate and identifiable regions along with glasses within each region
^F{)&# 4
will be discussed. The goal for this paper is to make glass selection easier to understand.
