Abstract:
A high refraction low dispersion optical glass, the components thereof including, by weight percentage: B 2 O 3 : 1-30%; SiO 2 : 0-20%; La 2 O 3 : 25-55%; Gd 2 O 3 : 5-40%; Y 2 O 3 : 0-25%; Yb 2 O 3 : 0-10%; Ta 2 O 5 : 0-10%; Nb 2 O 5 : 1-30%; TiO 2 : 0-10%; ZrO 2 : 0.5-20%; WO 3 : 0-10%; ZnO: 0-15%; R 2 O: 0-10%; RO: 0-10%; Al 2 O 3 : 0-10%; GeO 2 : 0-10%; Bi 2 O 3 : 0-10%. A high refraction low dispersion environmentally friendly optical glass having excellent light transmittance may be obtained by reducing the Ta 2 O 5  content within the glass components and introducing suitable amounts of rare earth oxide components having a high refraction low dispersion effect.
