Abstract:
A high refraction low dispersion optical glass having a refractive index of 1.86-1.92 and an Abbe number of 36-42. The components of the optical glass comprise, 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%; Al 2 O 3 : 0-10%; GeO 2 : 0-10%; Bi 2 O 3 : 0-10%. The optical glass does not contain PbO or F. A high refraction low dispersion optical glass having excellent light transmittance may be obtained by introducing suitable amounts of rare earth oxides having a high refraction low dispersion effect and optimising the proportions of said components.

Claim (Index 7):
The optical glass according to  claim 1 , wherein the glass refractive index ranges from 1.87 to 1.91, and the Abbe number ranges from 37 to 41.
