Designation Of Glass Types

Our optical glasses are classified by their main chemical components and are identified by refractive index (nd) and Abbe-number (Vd). Primarily they can be divided into groups, and further they can be identified into various types. Each group has a name and a code, and each type of glass within some group is named by the abbreviated group symbol and an Arab number. We classified them into 18 groups according to their positions on nd- Vd situation chart and their main chemical components.
