Abbe Dispersion
Explanation for the meaning of Abbe Dispersion
Definition of the Abbe Dispersion Value (Chromatic Aberration)
One very important property of an "optical material" is the Abbe value. It
is a measure of the degree to which light is dispersed when entering a lens.
The dispersion occurs at any time when white light is broken into its
component colors. The lower the Abbe value, the greater the dispersion of
light, causing chromatic aberration (color fringing) in the periphery of the
lens.
The higher the Abbe value, the better the peripheral optics will be. The
lower the Abbe value, the more chromatic aberration will be a characteristic
of that lens.
Many plastic materials have Abbe values of roughly 58. Most high index
materials have a much lower Abbe value of 36.
