Description

technical field [0001] The present application relates to the field of optical elements, more specifically, to an optical imaging lens. Background technique [0002] With the upgrading of portable devices and the development of image software functions and video software functions on portable devices, the hardware level of these devices is also continuously improved. Portable devices such as mobile phones are usually provided with a camera module so that the mobile phone has a camera function. A charge-coupled device (CCD) type image sensor or a complementary metal oxide semiconductor (Complementary Metal Oxide Semiconductor, CMOS) type image sensor is generally provided in the camera module, and an optical imaging lens is provided. The optical imaging lens can gather light from the object side, and the imaging light travels along the optical path of the optical imaging lens and irradiates the image sensor, and then the image sensor converts the optical signal into an elect...
