Background
With the development of science and technology, people have higher and higher requirements on the imaging quality of portable electronic products, and electronic products such as mobile phones and tablet computers become thinner and smaller in size. The performance of the currently used photosensitive elements such as CCD (charge-coupled device) or CMOS (complementary metal-oxide semiconductor) image sensors is also increasing and the size thereof is gradually decreasing, so that the corresponding camera lenses also meet the requirements of high imaging quality and miniaturization.
In order to satisfy the miniaturization, it is necessary to reduce the number of lenses of the imaging lens as much as possible, but the lack of freedom in design due to this makes it difficult to satisfy the market demand for high imaging performance.
