Abstract
An optical boroaluminate glass article comprises: from greater than or equal to 10.0 mol % to less than or equal to 30.0 mol % AlO; from greater than or equal to 10.0 mol % to less than or equal to 55.0 mol % CaO; from greater than or equal to 10.0 mol % to less than or equal to 25.0 mol % BO; from greater than or equal to 0.0 mol % to less than or equal to 30.0 mol % SiO; and from greater than or equal to 1.0 mol % to less than or equal to 20.0 mol % refractive index raising components. The optical boroaluminate glass article has a refractive index of the glass article, measured at 589.3 nm, of greater than or equal to 1.62, and a density of less than or equal to 4.00 g/cm.
