PROBLEM TO BE SOLVED: To easily release a film from a molding die and to improve the production efficiency without decreasing the spectral reflection characteristics in the method of forming a thin film of a composite aspheric lens. SOLUTION: A thin film sheet 15 with a thin film formed by vapor deposition is adhered to the molding face of a die 11, while a spheric lens 13 as the base is fixed to the molding face of a die 12. A fused resin 14a is dropped on the spheric lens 13, the dies 11, 12 are closed, the resin 14a is hardened, and after the resin is hardened, the dies 11, 12 are detached. |
