| description | The invention provides a low-specific-gravity phosphorus crown optical glass for precision mould pressing, a preparation method of raw materials and an optical element. The optical glass is characterized by comprising the following components in percentage by weight: 65-75% P2O5, 9-20% Al2O3, 2-10% of B2O3, 0-5% of BaO, 0-5% of CaO, 1-8% of K2O, 1-10% of Na2O, and 0-0.5% of Sb2O3, wherein the content of BaO and CaO is 0-5%, the content of K2O and Na2O is 3-18%, and the ratio of K2O/Na2O is 0.6-1%. The optical glass has the characteristics of small coloring degree, good stability, excellent process performance and suitability for batch production, and is mainly used for eliminating chromatic aberration in a lens group to achieve the purpose of correcting chromatic aberration. The inventionmainly solves the problems that the specific gravity of the existing phosphate system glass is not beneficial to weight reduction of a lens group and the production difficulty is increased.
