Optical lens comprising polycarbonate copolymer resin composition
2017
An object of the present invention is to provide an optical lens comprising a polycarbonate copolymer resin composition having high transparency, high refractive index and low birefringence. The composition contains 50 to 2 mol% of a structural unit represented by the following formula (I) and 50 to 98 mol% of a structural unit represented by the following formula (II), and has a specific viscosity of 0. The thickness of the central part made of a polycarbonate copolymer resin composition having a 5% weight reduction temperature of 350 ° C. or higher measured at a heating rate of 20 ° C./min of 12 to 0.40 is 0.05 to 2. An optical lens having a diameter of 0.0 mm and a lens diameter of 1.0 to 10.0 mm. [Selection figure] None
