▎ 摘  要

NOVELTY - A high-resolution optical lens comprises 14-16 pts. wt. alum, 14-18 pts. wt. soda ash, 4-6 pts. wt. nano silica, 8-12 pts. wt. modified graphene, 35-40 pts. wt. quartz sand, 4-6 pts. wt. boron trioxide, 7.5-8 pts. wt. zinc borate, 8-10 pts. wt. tungsten boride, 5-8 pts. wt. yttrium oxide, 5-8 pts. wt. iron carbide, 4-6 pts. wt. magnesium fluoride, 1-2 pts. wt. gallium nitride, 4-5.5 pts. wt. cobalt oxide and 2.5-3 pts. wt. calcium sulfate whisker. USE - High-resolution optical lens (claimed). ADVANTAGE - The high-resolution and transparent optical lens has high hardness and weak polarization. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation of high-resolution optical lens, which involves adding modified graphene and calcium sulfate whisker to melting furnace, melting, heating at 1000 degrees C to obtain modified graphene, heating at 800-850 degrees C, melting at 1250-1340 degrees C for 30 minutes, molding the molten material into lens shape and cooling to room temperature at the rate of 30 degrees C/minute to obtain optical lens.
