Abstract
Glasses containing silicon dioxide (SiO2) and/or boron oxide (B2O3) as glass formers and having a refractive index nd of greater than or equal to 1.7, as measured at 587.56 nm, and a density of less than or equal to 4.5 g/cm3, as measured at 25° C., are provided. Optionally, the glasses may be characterized by a low optical dispersion, a high transmittance in the visible and near-ultraviolet (near-UV) range of the electromagnetic spectrum, and/or good glass forming ability.
