Glass selection tends to be both a science and an art. It is the intent of this paper to remove the +eVYy_bL-
"mystique" surrounding glass selection, primarily based on the chromatic properties of the glass, \JLGw1F
and to show via careful parametric analyses how we can optimally select glasses for lenses of |}zWH=6
different f/numbers, spectral bands, and performance requirements. The important roles of 5es t
refractive index and Abbe number as well as partial dispersion will be considered. Using the )JMqC+J3*t
SCHOTT glass map, six separate and identifiable regions along with glasses within each region +C~h(
will be discussed. The goal for this paper is to make glass selection easier to understand.
