Niobium oxide in optical glass manufacture

International Symposium Niobium'81

Within recent years, niobium oxide has been widely used as a raw material for lanthanum borate glasses, which are typical optical glasses having high refractive indices and a relatively low value of optical dispersion. These types of glasses have been highly developed in recent decades and are now used extensively for camera lens systems, objective lenses of optical microscope, etc... (AU)
