Description of Related Art

As camera modules being widely utilized, the applications of the camera modules for various intelligent electronics, car devices, recognition devices, entertainment devices, sports devices and intelligent home systems have become a trend of development in the technology, especially the portable devices which have satisfied most of the public's desires. In order to further enhance users' experiences, smart devices with one, two or even more than three lens assemblies are becoming the mainstream in the market and lens assemblies with various features to meet requirements in different applications are continuously in development.

Conventional lens assemblies with a wide view angle are usually equipped with spherical glass lenses having an aperture stop disposed near an image surface. Thus, overly large lens elements are required to retrieve light, and it becomes difficult to reduce the volume of the lens assemblies in order to achieve the goal of miniaturization. The view angles of the miniaturized imaging systems that are currently available are too limited and do not have sufficient imaging ranges. Therefore, the conventional optical lens has failed to meet the trend of the current development in the technology.
