Different optical glass homogeneity and purity of the glass material. Special technological methods allow to obtain optical glass from one to the other cooking with high accuracy of the refractive index in a wide spectral range. On the chemical composition of glass separated by silicate, lead, phosphate, germanate, teluritnye, chalcogenide, the refractive index at the crown and flint, the deviation of the relative partial dispersion at Kurtz and Lang glass.
