Abstract:
The invention provides a high-refraction low-dispersion optical glass with refractive index of 1.76-1.80 and Abbe number of 47-51. The optical glass, comprising the following components by weight percentage: 0-3% of SiO 2 ; 25-40% of B 2 O 3 ; 20-40% of La 2 O 3 ; 12-25% of Gd 2 O 3 ; 6.5-15% of ZrO 2 ; greater than 10% but less than or equal to 20% of ZnO; 0-5% of Ta 2 O 5 ; 0-5% of Nb 2 O 5 ; 0-10% of Li 2 O; less than 0.45 of (Ta 2 O 5 +Nb 2 O 5 )/(ZnO+Li 2 O); 0-10% of Y 2 O 3 ; and below 625° C. of glass transition temperature Tg. With reasonable component ratio, the high-refraction low-dispersion optical glass favorable to precision is molding with excellent transmittance can be easily enabled while realizing the required optical constant of the glass of the present invention.

Claim (Index 2):
The optical glass according to  claim 1 , further comprising 0-10% of GeO 2 ; 0-10% of Bi 2 O 3 ; 0-10% of Al 2 O 3 ; 0-10% of Na 2 O; 0-10% of K 2 O; 0-1% of CeO 2 ; 0-1% of Sb 2 O 3 ; 0-10% of RO, in which RO is one or more of MgO, CaO, SrO or BaO.
