The present invention relates to a method of adhering an optically transmissive substrate to a compatible substrate such as plastic or glass and the resulting optical elements. A pressure sensitive adhesive layer, which is optically transmissive and is pre-applied to the optically transmissive substrate, eliminates many handling problems associated with liquid adhesive. Particularly preferred optical elements in accordance with the present invention are optical memory products and optical isolators with dichroic polarizers.

Optical devices and their method of assembly

A method of producing a glass-plastic, laminated, ophthalmic lens structure in a continuous operation. A thin, flexible, plastic adhesive layer is applied to a glass element to form a composite body that is inserted in a cylindrical gasket in such manner as to fit snugly and be sealed from the ambient. A monomeric formulation is flowed onto the adhesive layer and cured to form a laminated lens blank.

Ophthalmic lens method

There are disclosed a method of bonding components having substantially different coefficients of thermal expansion, and composite articles thus produced. The components are bonded with the cured product of an adhesive formulation composed essentially of a hydrogenated epoxide, an acrylate or blocked isocyanate end-capped urethane oligomer and an amine curing agent. Optionally, the formulation may contain an accelerator, an epoxy diluent and other minor ingredients.
