METHOD FOR PRODUCTION OF POLYMERIC MATERIALS WITH REFRACTIVE INDEX GRADIENT FOR LIGHT FOCUSING ELEMENTS Russian patent published in 2004 - IPC

FIELD: manufacture of optical elements, applicable for production of polymeric materials with a refractive index section gradient. SUBSTANCE: the method consists in mixing of components and pouring in a mould. The mixture of epoxidian oligomer, glycidol ether of phosphoric acid and curing agent is cured at the following relation of the components: epoxidian oligomer - 100 mass p., diglycidol ether of phosphoric acids - 33.5 to 53.8 mass p., curing agent - stoichiometric amount, where triglycidilphosphate or triglycidilmethylphosphate is used glycidol ethers of phosphoric acids. EFFECT: simplified procedure of manufacture of optical light focusing elements. 1 tbl
