METHOD FOR PRODUCING COMPOSITE OPTICAL ELEMENT

摘要

A method for producing a composite optical element wherein an energy curable resin is formed on a substrate, which comprises a step of applying an energy curable resin (1) on the substrate (2) and giving an energy to the resin and a step of forming the energy curable resin on the substrate by the use of a mold. In an embodiment, in a step of applying an energy curable resin (1) on the substrate (2) and giving an energy to the resin, the energy is given in such a manner that the energy curable resin exhibits a viscosity in the range of 10<SUP>3</SUP> to 10<SUP>11</SUP> pascal·second immediately after the energy is given. The above method eliminates the need for an apparatus for use in evacuation or in the temperature control of a mold core, and also the need for the treatment after the forming.
