abstract:An Abbe diagram plots the Abbe number against refractive index for a range of different glasses (red dots). Glasses are classified using the Schott Glass letter-number code to reflect their composition and position on the diagram.
The relationsofsystemicresolutionto subdivisionnumber, gratingperiod, magnifying powerandtilt Angle are theoreticallydiscussedandexperimentallycheckedon the Abbecomparator.
