Description
本發明係與光學鏡頭有關，特別是指一種五片式成像鏡片組。The present invention relates to optical lenses, and more particularly to a five-piece imaging lens set.
最近幾年來，隨著手機相機的興起，小型化攝影鏡頭的需求日漸提高，而一般攝影鏡頭的感光元件不外乎是感光耦合元件(Charge Coupled Device,CCD)或互補性氧化金屬半導體(Complementary Metal-Oxide Semiconductor,CMOS)兩種，由於半導體製程技術的進步，使得感光元件的畫素面積縮小，小型化攝影鏡頭逐漸往高畫素領域發展，因此，對成像品質的要求也日益增加。In recent years, with the rise of mobile phone cameras, the demand for miniaturized photographic lenses has been increasing, and the photosensitive elements of general photographic lenses are nothing more than a Charge Coupled Device (CCD) or a Complementary Metallic Semiconductor (Complementary Metal). -Oxide Semiconductor (CMOS), due to the advancement of semiconductor process technology, the pixel area of the photosensitive element is reduced, and the miniaturized photographic lens is gradually developing into the high-pixel field. Therefore, the requirements for image quality are increasing.
傳統搭載於可攜式電子產品上的小型化攝影鏡頭，多採用四片式透鏡結構為主，但由於手機相機的畫素攀升得非常迅速，感光元件的畫素面積逐漸縮小，且在系統成像品質的要求不斷提高的情況下，習知的四片式透鏡組將無法滿足更高階的攝影鏡頭模組，並由於電子產品不斷地往輕薄化、高性能的趨勢發展。The miniaturized photographic lens that is traditionally used in portable electronic products mainly uses a four-piece lens structure, but since the pixel of the mobile phone camera climbs very rapidly, the pixel area of the photosensitive element is gradually reduced, and the system is imaged.
