品が知られている。2. Description of the Related Art In recent years, there has been an increasing demand for aspherical lenses in order to reduce the number of lenses and make them more compact. However, aspherical lenses are more difficult to polish than spherical lenses, and while plastic lenses made by injection molding can be mass-produced at low cost, they suffer from sink marks that occur after molding, which distorts the focal length. there were. As an optical component that compensates for this drawback, by interposing a curable resin between a mold having a desired optical shape and a glass base material and curing it, a hardening resin that has an optical surface on the surface of the glass base material is used. 2. Description of the Related Art So-called composite optical components are known, in which a synthetic resin layer is formed.

Composite optical components with a layered structure require a curing process twice during manufacturing, which increases production equipment, lengthens the process, takes up space, and takes time, leading to increased costs. I was invited. In addition, although conventional composite optical components in which the curable resin layer is a single resin layer are advantageous in terms of cost, the coefficient of linear expansion due to heat and moisture absorption between the glass base material and the resin layer is significantly different, and the resin The hardness of the layer was also low. Furthermore, even when a vapor-deposited film for antireflection was provided on the resin layer, the same problem as above occurred between the glass substrate or the vapor-deposited layer and the resin layer. For this reason, it lacks environmental resistance, and when a vapor-deposited film is provided, there is a problem in that wrinkles, film peeling, etc. occur.

In some cases, distortion occurs, distorting the glass substrate or causing cracks in the resin layer, making molding impossible.

The refractive index difference with the curable resin is -0.00
05 to +0.0005 and an Abbe number difference in the range of -1 to +1, the curable resin layer contains 5 to 70% by weight of transparent rubber elastomer powder particles, the content of which is highest on the base material side.

Furthermore, the particle size of the transparent rubber elastomer powder particles must be less than or equal to the thickness of the curable resin layer. Furthermore, the transparent rubber elastomer powder particles are preferably subjected to a general surface treatment using a polyfunctional silane coupling agent to improve adhesion to the curable resin. The transparent rubber elastomer used in the present invention is preferably one with good transparency, such as silicone rubber, ethylene propylene rubber, acrylic rubber, etc., and diene compounds,
Rubbers synthesized by copolymerization of dienes and other vinyl compounds, or rubbers crosslinked by sulfur vulcanization, peroxide, etc., can be used. Heat, electron beams, ultraviolet rays, etc. are used as energy for curing the resin. Depending on the application, a deposited film of SiO, SiO2, etc. may be formed on the curable resin layer by vacuum deposition or the like.

の制御が困難になる。[Function] In the composite optical component having the above structure, the polymerized curable resin layer has a uniform refractive index and Abbe number,
It is optically uniform. If the refractive index difference and Abbe number difference between the curable resin and the transparent rubber elastomer powder particles are outside the ranges of -0.0005 to +0.0005 and -1 to +1, respectively, color dispersion and scattering due to reflection will occur, making it difficult to put into practical use. It becomes impossible. In particular, compared to a curable resin that does not contain transparent rubber elastomer powder particles, as the content of transparent rubber elastomer powder particles increases, the thermal and water absorption coefficients of linear expansion and curing shrinkage of the curable resin decrease. . This is due to the fact that the content ratio of the curable resin component is reduced due to the inclusion of transparent rubber elastomer powder particles, and the interaction between the resin and inorganic matter, similar to the case with inorganic-containing resin materials used for structural members, etc. . Here, if the content of the transparent rubber elastomer powder particles is less than 5% by weight, the effects of lowering the thermal and water absorption linear expansion coefficients and curing shrinkage ratio cannot be obtained. On the other hand, when the content of transparent rubber elastomer powder particles exceeds 70% by weight, the average viscosity
Workability deteriorates due to the effects of thixotropy, etc., making it difficult to control the surface shape.

じない。[0010] By distributing the transparent rubber elastomer powder particles in a gradient manner such that the content is higher on the base material side and becomes smaller as it approaches the surface, the base material side has large rubber elasticity, and the coated surface The closer you get, the smaller the rubber elasticity becomes, and the coated surface has the lowest rubber elasticity and the highest hardness. This eliminates wrinkles and film peeling due to insufficient hardness, which were problems on the coated surface, and allows the rubber elasticity to absorb distortion, which was a problem on the base material surface, and prevents cracks in the curable resin layer. can be prevented. Furthermore, if the transparent rubber elastomer is subjected to a surface treatment, the adhesion between the transparent rubber elastomer and the curable resin will be increased, and peeling at the interface will not occur.

There are various methods, such as a method in which the curable resin is laminated on a substrate in order of increasing content and then cured, and a method in which transparent rubber elastomer powder particles are sedimented by gravity, centrifugal force, or the like.
