Abstract

PURPOSE:To improve the adhesiveness between a glass substrate and resin layer and to prevent the exfoliation of the resin layer even after long-time resting in high-humidity environment by pressing the glass substrate by the resin layer from the outer periphery or both sides. CONSTITUTION:The resin layer 20 of a composite type aspherical lens consisting of the glass substrate 10 formed as; for example, biconvex lens and the resin layer 20 formed of the polymer layer of an acrylic UV curing resin is formed on a face 11. After the face 11 and face 14 are treated with a silane coupling agent, the resin layer 20 and a 2nd part 21 which is part thereof are tightly adhered and formed thereon. The end 21 of the resin layer 20 presses the glass lens 10 from the outer periphery of the lens 10 and, therefore, the adhesiveness between the lens 10 and the resin layer 20 is improved. The exfoliation of the resin layer even after the long-time resting in the high-moisture environment is thereby obviated.

Various types of composite optical members as described above have been proposed. Here, the bonding surface between the glass substrate and the resin layer needs to maintain sufficient adhesion against stress caused by curing shrinkage during molding, environmental changes, and changes over time. In order to obtain this sufficient adhesion, the surface of the glass substrate is treated with a silane coupling agent to activate it against organic compounds, and a resin layer is formed on the surface of the glass substrate. It is disclosed in Japanese Patent No. 54-6006. The first cross-sectional view of an aspherical biconvex lens is an example of the composite optical member.
Shown in Figure 0. This aspherical biconvex lens uses a glass substrate (
The surface (11) forming the optical element (10) is treated with a silane coupling agent, and a resin layer (20) of a polymer of methyl methacrylate monomer is formed thereon. (30) is a lens chamber that holds this lens, and (31) is a tightening screw ring that fixes the lens in the lens chamber (30).
