glass selection
Glass selection tends to be both a science and an art. It is the intent of this paper to remove the vEX|Q\b6' "mystique" surrounding glass selection, primarily based on the chromatic properties of the glass, &T5fH!?4 and to show via careful parametric analyses how we can optimally select glasses for lenses of -%7Jj;yA different f/numbers, spectral bands, and performance requirements. The important roles of Y8{T.\%\+ refractive index and Abbe number as well as partial dispersion will be considered. Using the M^!C?(Hx^x SCHOTT glass map, six separate and identifiable regions along with glasses within each region A?^A*e will be discussed. The goal for this paper is to make glass selection easier to understand.
