RESIN COMPOSITION FOR HYBRID LENS, METHOD FOR PRODUCING HYBRID LENS, HYBRID LENS AND LENS SYSTEM

WIPO Patent Application WO/2004/095087

A1

A resin composition for a hybrid lens which comprises a radically polymerizable monomer and a silane coupling agent, wherein the radically polymerizable monomer preferably comprises a specific di(meth)acrylate compound and a specific mono(meth)acrylate compound; and a method for producing a hybrid lens which comprises using a mold for molding a hybrid lens in which a glass lens base material and a glass mold for transferring a non-spherical surface are oppositely arranged, packing the above resin composition for a hybrid lens between them, irradiating the composition with an ultraviolet ray from both the glass lens base material side and the glass mold site, to form a hybrid lens having the glass lens base material and, joined thereon, a resin layer. The method allows the production of a high performance hybrid lens which has a thick resin layer, has a large difference between the minimum and the maximum thickness of the resin layer, and has a large area of a non-spherical surface.
