Rare Eart Oxides

Optical materials generally consist of one or two basic chemicals, such as glass-metal oxides and more than ten other metal oxides, which are to rare-earth oxides or rare oxides (scattered and rare in nature, which is called the noble), as well other chemicals of high purity content of the main chemical, without which the optical quality of the material is not possible.
