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 glass has an excellent transmittance when the content of Ta 2 O 5  in glass component is reduced. The optical glass comprises the following components by molar percentage: 40-65% of B 2 O 3 ; 6-21% of La 2 O 3 ; 1-15% of Gd 2 O 3 ; greater than 6.5% but less than or equal to 15% of ZrO 2 ; ad 10-28% of ZnO. According to the present invention, the transmittance of glass becomes excellent without introducing SnO 2 ; the product cost is optimized by reducing the content of Ta 2 O 5 ; with reasonable component ratio, the high-refraction low-dispersion optical glass in favor of precision molding and with excellent transmittance, as well as the glass preform and optical element made of the optical glass can be easily enabled while the required optical constant of the glass is realized.

Claim (Index 1):
