Optical glass and optical element

Abstract

An optical glass is provided. The optical glass is suitable for use in optical elements including lenses, prisms, light guide rods, arrays, optical fibers, gradient components and optical windows in the fields of imaging, sensor technology, microscopy, medical technology, digital projection, telecommunication, optical messaging technology/information transmission, optics/illumination in the automotive sector, for solar technology, photolithography, steppers, excimer lasers, wafers, computer chips and/or integrated circuits and electronic instruments which contain such circuits and chips. The optical glass contains the components La2O3, B2O3, GeO2, HfO2 and In2O3 and in which the following components are present in the following proportions, in % by weight on an oxide basis: SiO2O2 1-8; Sb2O3 0-<2; SiO2+B2O3 1-<20; and SiO2+B2O3+GeO2+HfO2+In2O3 15-25.
