(従来技術)
従来、非球面レンズは、その光学的効果を評価されなが
らもガラスを直接非球面に加工することが困難な為量産
出来ず、特殊な用途に限定されていた。(Prior Art) Conventionally, aspherical lenses have been highly evaluated for their optical effects, but because it is difficult to directly process glass into an aspherical surface, they cannot be mass-produced and have been limited to special uses.
そこで、レンズ素材を光学樹脂として金型を用いて成形

フォーカスが狂ってしまうという欠点があった。Therefore, the lens material is made of optical resin and molded using a mold to produce bi-products.However, lenses made only of optical resin have a change in refractive index and radius of curvature of the surface due to changes in the ia degree. The disadvantage was that the focal length and back focus would be distorted.

Manufactured.
しかし、樹脂層形成の際の重合収縮や、温度変化による
ガラスと樹脂との熱膨張率の違いから、その接合境界面
から剥離したり、ガラス及び光学樹脂に破損を生ずると
いう問題があった。However, due to polymerization shrinkage during the formation of the resin layer and differences in thermal expansion coefficients between the glass and the resin due to temperature changes, there have been problems such as peeling from the bonding interface and damage to the glass and optical resin.

ズとする方法等が考えられている。To solve this problem, after applying a primer that improves adhesion to the resin of the glass base material and the layer forming surface, we used a soft optical resin that can easily follow the difference in thermal expansion coefficient to form the resin layer. A method of forming a multilayer composite lens, and a method of forming a protective layer of a hard optical resin on the soft optical resin to form a multilayered composite lens, etc. are being considered.

増加するという問題点があった。(Problems with the prior art) However, in the above conventional configuration, in the former method,
The stability of the resin layer makes it difficult to maintain optical performance, and it is easily scratched, so it requires careful handling, and the latter method complicates the manufacturing process, resulting in poor productivity and increased manufacturing costs. There was a problem with that.
