Abstract
PURPOSE:To form an optical surface with high accuracy by previously forming layered films consisting of an inorg. material which can maintain a tight contact state on the surface of a molded elastic body during the period when molds are parted and is soluble in water or org. solvent on the surfaces of the molds to be used for forming and curing the elastic body layer, which surfaces come into contact with the elastic body raw material. CONSTITUTION:The respective molds consisting of the upper mold 13, the lower mold 14 and the side mold 15 are combined and disposed. A hydrophobic material for the elastic body which has no hydrophilicity and forms the elastic body 1-1 is poured into the inside space of the molds. After the material for the elastic body 1-1 poured into the molds is cured, the upper mold 13 is removed and a bottom plate 2 is installed. The raw material for the elastic body 1-2 is then poured into the space between the upper surface of the elastic body 1-1 and the bottom plate 2. The lower mold 14 and the side mold 15 are successively parted from the elastic body 1 have the double- layered constitution upon curing of the elastic body 1-2 and thereafter, the protective layered film sticking to the surface of the elastic body 1 is completely removed and dried, following which the elastic body is inserted into an outside cylinder 16 and the element is completed. The element having the high-accuracy optical surface is thereby obtd.
