In first embodiment to the 5th embodiment, the Image Sensor 20 of selection is 12,000,000 (shown in Figure 11) Pixel, pixel size are 1 micron * 1 micron, and the diagonal distance in effective image sensing area is 5mm.

In first embodiment to the pick-up lens 10 of the 5th embodiment, there is positive light coke and negative light due to multiple The lens mixing arrangement of focal power, meets pick-up lens 10 to high-resolution, the demand of ultrathin, and can ensure pick-up lens 10 have preferable image quality.Pick-up lens 10 can be used as ultrathin telephoto lens and use.

1 is please referred to Fig.1, the pick-up lens 10 of the utility model embodiment can be applied to the utility model embodiment Electronic device 100.In other words, electronic device 100 includes the pick-up lens 10 of Image Sensor 20 and any of the above-described embodiment. Pick-up lens 10 is aligned with Image Sensor 20.

Specifically, complementary metal oxide semiconductor (CMOS, Complementary may be used in Image Sensor 20 Metal Oxide Semiconductor) Image Sensor or charge coupled cell (CCD, Charge-coupled Device) Image Sensor.Pick-up lens 10 be aligned with Image Sensor 20 including：The optical axis and image sensing of pick-up lens 10 The centre normal of device 20 overlaps.

The electronic device 100 of the utility model embodiment includes but not limited to for mobile phone, smart phone, tablet meter The electronic device of the supports such as calculation machine, laptop computer, laptop, smartwatch imaging.

In the above-described embodiment, pick-up lens 10 can be applied individually to any in electronic device 100.In other embodiment In, pick-up lens 10 (pick-up lens 10 of the utility model embodiment is telephoto lens) also can be with the wide-angle with short focus Camera lens is conjointly employed in electronic device 100, to achieve the effect that optical zoom.Specifically, when electronic device 100 is for obtaining When image, user can select and switch between different shooting functions (taking the photograph remote or wide-angle) according to self-demand, and Related algorithm be can allow to achieve the effect that optical zoom.

In some embodiments, electronic device 100 meets conditional：

1.5≤TTL/IMA≤3.1；

Wherein, IMA is the diagonal distance in effective image sensing area of Image Sensor 20.

In other words, TTL/IMA can be [1.5,3.1] range in arbitrary value, such as the value can be 1.5, 1.7,1.9,2.1,2.3,2.5,2.7,2.9,3.1 etc..

As TTL/IMA ＜ 1.5, it is difficult to correct each aberration, especially curvature of the image, distortion aberration；As TTL/IMA ＞ When 3.1, the overall length of pick-up lens 10 is long, leads to the whole enlargement of pick-up lens 10.Meet the above conditions, it can be preferably Each aberration is corrected, and can realize the ultrathin of pick-up lens 10.
